5w 30 the trick is to keep the temperature down

Re: POLL: which oil do you use ?
 

Just curious what engine you are running...oil temps and pressure....are you set-up to run that low of a viscosity..journals..oil pump...coolers? If you are running 11 qt oil pans and a high volume pump you may be ok with a Super premium Synthetic 5W-30 in a big marine engine.

Just curious. the lowest viscosity I have seen used is a
10W-40 Super Premium.

Illmor tested the Dodge Viper marine engines and found the 10W-30 for street was not sufficient to develop a proper film at constant nearredline use.. so they moved up to 15W-50 Mobil-1.

Re: POLL: which oil do you use ?
 

I run straight 30 weight dinosaur oil.
At up to 260 peak horsepower, my engines deserve no less.

That and the manufacturer recommended it before they went under.

Re: POLL: which oil do you use ?
 

Some very intensive tests show now that 5W-30 or 10W-30 synthetic oil such as Mobil-1 are equal or better than 30wt dino juice. If you have 260HP you probably have a 350 Chevy that could easilly take a 15W-40 or 15W-50 either of which is superior to 30wt.

Teague says if you use straight weight oils to use:

30wt for cool climates
40wt for moderate climates
50wt for hot climates.

If you go straight conventional he is correct in these suggestions. :D

Re: POLL: which oil do you use ?
 

Should I use multi-vis Hydro?

You are the freaking Pope of oil. :D

Re: POLL: which oil do you use ?
 

Truly..I think only multi-vis if synthetic.

Otherwise..

30wt 70*F
40Wt 80*f
50WT 90*F

Re: POLL: which oil do you use ?
 

I figured I was the "Pope of oil" when the white smoke started pouring out the back end of my boat... ;)

Re: POLL: which oil do you use ?
 

Did you buy a boat? What did you get?

Re: POLL: which oil do you use ?
 

I use Straight 50w and change approx 20 hours no problems yet!

Re: POLL: which oil do you use ?
 

I am on the waiting list for a new Skater... I figured all or nothing...

Re: POLL: which oil do you use ?
 

Great - congratulations. Size? Have you picked power?

Re: POLL: which oil do you use ?
 

40'er...kinda like this one...working on a paint scheme..
..they say they have these 1150 V-12's...160mph...but more realistically I think Sterling 1050's..

Re: POLL: which oil do you use ?
 

Very nice. Do you have an approximate delivery?

Re: POLL: which oil do you use ?
 

Have not chosen power yet..on the so called list...delivery date is a ways out...it may be moved up or back...but right now all they say is you can expect to have one...after a few special projects are completed things will get firmed up.

My second choice is a NorTech if things get too "futuristic".


...I really do like the Skater's ride and handling..but a Nor Tech is great too.

Re: POLL: which oil do you use ?
 

Either will be a great choice.

Re: POLL: which oil do you use ?
 

Mobil1 is junk!

Now that I have my FLAME suit on... here are the facts. Mobil1 has the greatest marketing strategy in the industry. They PAY the manufacturers to use their oil. Think how much the manufacturers save by getting the first fill for free. Then all they have to do is get the rest of the world to believe in their hype and the payoff is big.

The truth is that Mobil1 has some of the worst shear stability in the industry. They filter it and make it nice and clear to pour so you think you are getting something more than what you are.

Royal Purple is the oil I use in everything I own.

So, you ask... "Why is Mobil1 so bad and HOW do I know this...?"

In several different applications of professional racing, I tried Mobil1 back to back in both dyno and real world track racing at high rpm. In one vehicle, a Dodge Neon DOHC, the cam actuates a roller rocker arm which floats against a hydraulic lash adjuster and the other side the valve. The cam lobe provides leverage to open the valve but true valve lift is determined by how well the oil maintains its hydraulic properties. If the oil breaks down, so does the actual lift at the valve. This was very evident on the dyno but more so at the track. At Texas World Speedway the temps would exceed 240 degrees oil temp and the pressure would drop from 65 psi cold to 35 psi hot. The idle pressure would drop to less than 5 psi and take 30 minutes of idling to stabilize pressure. This was using the 15W/50 oil.

By switching to Royal Purple, we never saw an oil temp over 200 degrees and our coolant temps dropped from 210 degrees to just over the thermostat temp of 185 degrees. On the dyno our power actually increased from 185hp to the front wheels to 205 hp just from the added lift and the lower parasite drag due to using a LOWER viscosity oil. Thats right... we used a lower viscosity oil which saved drag and still gave us the full hydraulic properties needed to support high rpm and high stressed loads.

Now for a real engine... In our Dodge Vipers, we saw a 60 hp gain across the board and a massive temperature drop due to the aluminum block and heads. The oil covers more area than the coolant thus offering a much greater cooling for the engine. In all our races, we would keep the stock radiators and not use a larger capacity front radiator which would add 25 pounds ahead of the front wheels.

Want more proof...? In 2000, BMW switched to the Mobil1 oil from their Synthetic Castrol for the BMW M3. Amazingly, owners all over the United States were having catastrophic engine bearing failures. At first, it was blamed on the owners overrevving the engines.... but, once it was found out that the only ones having these failures were those using the factory recommended Mobil1 oil, it was determined through several different analysis strategies that the oil was to blame. BMW's fix was to replace all the M3 owner's oil with Castrol synthetic 5W/50 and the failures went away.

Look, if it works for you, great. My experience is that its junk and it loses power and protection. Added heat is added trouble and wear. Royal Purple's parent company is Synerlec, the STANDARD in heavy industry and compressor oils for the largest oil producing companies. Don't take my word... look it up on the internet.

Cool. Will Loucks be painting the boat? Any renderings you can post? It will be one sweet ride.

Re: POLL: which oil do you use ?
 

First I have to close on the sale of 2 companies...then finalize things...but it will happen...I am thinking up ideas and I will use their paint guys....

Re: POLL: which oil do you use ?
 

hey Dave...quite a manifesto... :D

Re: POLL: which oil do you use ?
 

I find it interesting that one of the worlds most renowned race engine builders would deliver their engines with an oil that is junk, versus an oil that would gain them 60HP.

I have the number for one of the main engineers at Ilmor, Maybe they will want to hire you. :evilb:

Re: POLL: which oil do you use ?
 

Swepco 20/50 306 oil , would'nt use anything else. awesome results with this oil in migh performance marine engines.

Re: POLL: which oil do you use ?
 

...I think this was seen in his neighborhood :D

Re: POLL: which oil do you use ?
 

Thats some funny stuff Hydro. What do you know about swepco?

Re: POLL: which oil do you use ?
 

Southwestern Petroleum Corporation...SWEPCO offers several oils including high-performance 15W-40 and 20W-50.

The 15W-40 is API rated CG/SJ; CF-2, Mack EOM and Cummins CES ...it would be great for marine use.

The 20W-50 is not API rated and here is what I have found out about it:

It is a high performance oil with a high level of friction reduction additives that started off as a paraffinic based oil as opposed to a PAO or ester. It's base has a lot in common with PAO's so the base oil is comparable to Mobil-1 or Amsoil's.

Additives:
Magnesium: 6
Phosphorous: 1384
Zinc: 1747
Calcium: 3227
Moly: 146

Cst's @ 100*C 70

This sample of Swepco 20W-50 would compare to the base and additives expected to be seen in Premium Synthetic oils such as Amsoil Severe Service 20W-50 Racing; Royal Purple 20W-50 racing; Redline 20W-50 or Mobil-1 20W-50 V-twin. I am awaiting test results from Alisyn as well.

All of the above oils including Swepco would reduce friction and keep bearings cool and are the best 20W-50's around.

Re: POLL: which oil do you use ?
 

Hydro you are exactly correct about Swepco, Does not mix with h2o, drive oil is also awesome, oil sticks to everything reducing wear upon initial start, looks as good after 30 hours as it does at new. I have found it to increase power somewhat and bottom line protect my large investment in my motors. Nortech has switched exclusively to it as well as numerous other builders. Ron Potter would not switch if it was'nt the best. just bought 11 cases of it, and have alot of high performance boaters have changed to it at LOTO. Wiggler

Re: POLL: which oil do you use ?
 

Anyone that knows offshore engines knows a premium synthetic oil with the right additives is what adds durability.

What does a quart of 20W-50 Swepco cost you guys and where are you buying it from?

Are you guys running K & N oil filters? They seem to be the best trade off between excellent flow and good trapping...certainly better than the Frams they say.
Dual bypass flitration is really the way to go however.

Re: POLL: which oil do you use ?
 

Hopefully their high performance oil is better than their low end commercial cheap sh!t. It's good to hear something about them, b/c we never hear anything about them unless they are cutting our nuts on price for the Mobil Delvac 1300 Super 15w40. God, you gotta love competition.

Re: POLL: which oil do you use ?
 

It's amazing. Roger Penske sold Detroit Diesel for 2.5 billion... All Detroit's ever used is Mobil product. Roger also owns a big stake of Ilmor. They machine his team engines. All they use is Mobil 1. Trust me, ExxonMobil does not pay GM or any other company to put their oil in the cars. Everyone of them pay for that prodcut. The factory approval process is rigirous.

Now when I have been to ExxonMobil testing facilities, the difference in hp and wear are amazing when they break the engine's down. This is one of the first times, I have heard so many tierrible stories. There are many magic tricks in the oil business... The old egg beater tricks still seem to work. It all comes down to the personal preference, and as I have stated in the past "whatever gives you the warm fuzzy feeling inside"

Re: POLL: which oil do you use ?
 

Some say an emulsion is better than seperation for both water and gasoline contamination. I feel if water or gas is in there the best thing to do is test and get it out.

Re: POLL: which oil do you use ?
 

10 quarts Kendall GT 40 with one gallon of Lucas oil treatment and Fram filters. Change every 10-15 hrs.

Re: POLL: which oil do you use ?
 

..how about 10qts of Kendall Straight 40 with a K&N filter and hold the Lucas please.. :D

Oil froth is a disasterous situation...look at the right side below with Lucas added...it's froth city. Froth is air and oil forming into a useless foamy mess... the Scaaeffer's additive on the left works good however. The goal is to help the lubricants "climb" into lifters etc. not foam all over the place. :eek:

My personal opinion...save your money and buy a better premium synthetic oil that will actually do something for your offshore engine. It's all I will recommend anymore.

Re: POLL: which oil do you use ?
 

What's that a picture of? I'll tell you.....everybody has an opinion and an experience. I've never had that one. These are huge blower motors that I'm using that combo in. What oil temperature and pressure was the motor run to make the Lucas do that?

Re: POLL: which oil do you use ?
 

The product on the left did not foam under the same conditions..that's enough for me...if you like it use it...I won't so there will be on the shelf for you. :D

Re: POLL: which oil do you use ?
 

A guy who knows me laughed his butt off at my postings here and the interest that has been generated around the subject of oil...he said before reading all this he thought the oil did all the work and now feels the additives are perhaps more important than the base oil itself.

Well he is exactly about 50% right. When the anti-wear additives are contaminated or molecularly "spent" the base oil is next to near useless and breaks down fast....and vice versa...so oils with high base contant complement a great additive package.

Adding a ton of great additives to a lesser base-stock however... "is like putting perfume on a pig". :D

Re: POLL: which oil do you use ?
 

Mobil 1
Been using it for over 20 years in my Car's, Truck's, Boat's and now my H-D V-Rod. Back in the 80's I ran it in a couple of turbo car's that are very hard on oil and never had a single issue. Yukon now has 180K miles without an issue and still running storng. My Z06 had it as a factory fill and I continue that at regualr intervals.
As stated previously the only drawback is the extra price but, to me it's an investment in reliability and longevity. small price to pay and worth the little extra to me.

Re: POLL: which oil do you use ?
 

My best friend and I both have 575SCis with 300 hours. His is modified to 650HP; mine to 750HP.
He used Mobil 1 for the 1st 150 hrs. and switched to RP 20W50 with excellent results.
I bought mine used with 76 hours, and can't remember what the former owner used in it. I have used RP 20W50 ever since with no oil related problems. We use RP 70W90 MaxGear in our superchargers, and K&N 6002 filters. We have stuck with Merc HP semisynthetic gear oil in the Bravos, again with good results. We change oil, blower oil, and gearcase oil every 25 hours.
Some of our friends have started running RP Max Gear in their Bravos as well.
I'm not shilling for RP, it just seems to work very well for us,
plus their bottles match my boat :D !
Regards,
Steve

Re: POLL: which oil do you use ?
 

I had a higher opinion of Royal Purple 20W-50 until Mike at Sterling said they did not like it's tendency to repel gasoline in the engine or water leaking into the drive/engine. It could set the stage for corrosion. I never used it much but he got my attention.

Mobil-1 seems to be a favortie because it is so widely used in autos and now in marine engines. The new formulation of 15W-50 M-1 EP is great. No surprises.

Re: POLL: which oil do you use ?
 

Royal Purple 7-10 hp on the dyno vs Mobile1
