Re: Marine Lubrication
 

Another one Hydro, Valvoline VR-1 Racing in the 20W-50, and the VR-1 straight 50 ? Info ? and opinions.

While we're at it, how about Lucas conventional and full synthetic oil stabilizers ?

Re: Marine Lubrication
 

The Valvoline oils have a pretty weak add pack IMO. And just say no to oil additives.

Re: Marine Lubrication
 

This is the beloved crew of the Amsoil Racing Team :p

They said to use "Severe Gear" Gear Lube in outdrives that are seeing high torque and horsepower.

Anyone try it?

Re: Marine Lubrication
 

I have had customers run it in outboard lower units for a short time. I recommend more frequent changes running a non-marine gear lube as they are geared toward "less humid" applications.

FWIW: In automotive applications, both diffs and transmissions, the Severe Gear line of AMSOIL lubes is my first recommendation for people that are ordering AMSOIL from me.

Re: Marine Lubrication
 

I am thinking that Amsoil "Severe Gear" should be in Bravo Drives of High horsepower and torque and changed every 20 hours with the engine oil.

I would personally feel comfortable with the Amsoil Marine Gear Lube in boats with 425 HP or less.

Re: Marine Lubrication
 

Is this Fully Synthetic as you say, or not?

Re: Marine Lubrication
 

By definition and law Castrol "Fully Synthetic" is in fact considered fully synthetic. It is a Grade III bodering on the specs of a PAO.

It is better than conventional bases...better than synthetic blend bases...not as good as a PAO (Mobil-1, Amsoil RP etc)..or a fully ester such as Redline. But VERY CLOSE>!

For the money it's a real good deal at WalMart.

We are hearing that 15W-50 M-1 will be making a come back at Wally World.

Wally Land has Rotella 15W-40 for $9/gallon...great conventional product as we have found.

Re: Marine Lubrication
 

I'm going to be doing an oil sample. I usually suck my oil into a shared vacuum canister, so that wouldn't be purely my oil. I'd like to snake my drain hose throught the bilge drain, but can't easily get under the engine to do so (tight, tight quarters).

Can i snake a clear plastic tube down the dipstick hole, put my finger over the end, pull it back out, put that end in the sample bottle and release my finger, thus draining out a small quantity of oil from the crankcase?

Would the plastic hose contaminate the sample?

Is there an eaiser way?

Thanks in advance.

These pumps have been working real well.

Another thing that comes in real handy is if you have a remote oil filter you can put a petcock on it and get your sample.

Re: Marine Lubrication
 

Cool ..I had not seen those before! :p

Re: Marine Lubrication
 

Hydro In post 587 You recommended "MOTUL" 300v 15w50. Does this product have a "anti-corrosion package ?? Does it have a seals additive ??? Why were you so positive on its quality and then you haven't mentioned it again ?? CHEERS AW

Re: Marine Lubrication
 

The reason I do not talk much about it is.. whereas it's made using a "double-ester" process...amazing base-stock! It's cost is a bit prohibitive at $13.00/qt.

I do know guys who own and service High-performance Motorcycles; Porsche's and Ferrari's who swear by the stuff.

It may be the world's best 15W-50. But also hard to get around here.

You can get some here if you desire. It is a great product with perfect additives and great anti-corrosion additives for sure!

The only potential problem is that it is made in France I think :p

Re: Marine Lubrication
 

Hydrocruiser, have you any opinion on the Fuchs Silkolene oils? Ex: Fuchs Silkolene Pro R 15W-50

Re: Marine Lubrication
 

http://www.silkoleneoil.com/pdf/PRO%...04%20Wheel.pdf

I had not previously looked into this particular ester based synthetic oil. From the spec sheet it does look real good I must say.

It goes for 40.15 lire' per quart...you guys do the math! :D

Re: Marine Lubrication
 

Luckily it`s not that expensive here in Europe, about half. I am also looking at the Silkolene Pro 4 SX 15W-50 could you give me an opinion on that one? The brands you are using "over there" are not that easy to get a hold of here. So I am looking for a good high perf. oil that are easy to get here.

Thanks for a great thread :D

... and 1 US gallon of petrol is now about $ 7.50 so spending the extra $ on the oil is not that bad...

Re: Marine Lubrication
 

Ok, here is one for you oil gurus. I have a pair of 540 NA motors that I am putting break in hours on. The builder says that I should stay with the Valvoline Racing 40. What qualities does Mobil 15-50 or whatever version of Mobil that you recommend have over the Valvoline oil? I am using the Wix filters. I plan to change oil as often as is required. What are the oil change differences between the two? I thought that I read in a recent post that Valvoline has some undesireable qualities. Thanks.

Re: Marine Lubrication
 

I can only add this. I was running Valvoline in my NA 540 last year for the first 40 hours or so. Also recommended but I changed it at about 10, then every 15-20 hours there after, then again before winter. This year I switched to Amsoil 20w-50 Racing and WOW, what a diffeence. I'm running 34 MPH faster......just kidding of course.

However, what I did see was that the motor seems to rev quicker, which may not be an issue in a boat, but it does. It also starts much easier. With the Val. (I ran 50w Racing) I might have to restart 3-4 times when it was cold. By cold, I mean the motor, but the temps. The temps could be 100.

With the Amsoil I start it one time and it'll idle at 800-900 RPM and it's ready to go in just 1-2 minutes. With Val. I had to let it warm up at 1000-1200 RPM for a few minute it seems.
Been running it all season so far which is about 25-30 hours this year and it's great.

The other thing is oil pressure is much more stable. OP seems high when cold, but when it got good and hot after a hard run, would be lower than I liked. Now cold it's not as high, but hot it's barely any lower. Much more consistant in the 65-75 psi range. It seems to handle the heat much better.

It also seemed ot use about a quart every few hours, but nothing more than what Merc. says is OK for a 502. I had to top off with a little over 1/2 quart at about 9 hours. With Val. I would have gone through 2 quarts easy.

Nothing scientific, just what I've seen so far.

Re: Marine Lubrication
 

You just summed the major reasons to use the right synthetic oil for a specific application. You have a perfect match. Conventionals won't meet the needs you have very well at all.

Re: Marine Lubrication
 

SeaRay Jim - thanks for the extended response and for your input Hydro. It appears that there is no comparison between the two. As many hours as I put on in a year, I should be able to change the oil only 2x/yr.

I'm already running Amsoil in my Bravos.

Re: Marine Lubrication
 

FYI...Amsoil is now saying to use Amsoil "exterme gear lube" in high output offshore boat drives and change it of couse more frequently as it does not have the ability to handle much water very well... the Amsoil Marine Gear Lube is not for high HP/Torque output/" heavy offshore use"....and racing. Straight from the Amsoil reps who had a display tent at the St. Clair Michigan OSS race...

So in that case Mobil-1/RP/Torco/Redline are just as good as Amsoil's "extreme gear". Take your pick...unless you like Mercury HP....the synthetics have an edge probably...HP is semi-synthetic.

Amsoil's former Series 20000 Gear lube was a heftier product apparently than the current offering. Teague liked Series 2000 and I did too...it's like they reformulated Coke...why? :rolleyes:


I had a feeling about this... :p

Re: Marine Lubrication
 

Hydro,

I believe you are referring to the "Severe Gear" gear oil. This one: THIS ONE at AMSOIL

Re: Marine Lubrication
 

Yuppers..it's what the Amsoil reps said to use in offshore boat's Bravos...I personally have not heard from anyone here as to if they used it and how it works.

I must be honest wheras I can make recommendations on what oil to use...it seems there is no one gear-lube that is the "end all be all"...... atleast to me anyways. :D

Re: Marine Lubrication
 

got a thread going in GD, my oil distributor has 139 cases of mobil 1 20/50 v twin he is willing to let go for $36 a case, equals out to 6 bucks a qt plus shipping...let me know..Rob

Re: Marine Lubrication
 

I am interested! How do I order?

Re: Marine Lubrication
 

put your name and the case number on that thread, thats going to give me an estimated total by the end of next week. then I'll get the personal info and CC # and get everything shipped out. I'll let the thread run through next fri or sat, get payments run through and then pick up product on monday or tues, everything should be shipped by the fri after that...Rob

shop phone # is 866-776-3682 or you can email me at rob @ proformauto.com

Re: Marine Lubrication
 

Not a bad price for the M1 VT. The AMSOIL MCV typically runs about $7.75 SHIPPED per qt by the case of 12.

Re: Marine Lubrication
 

A bargain! :drink:

Re: Marine Lubrication
 

Anyone using Amsoils Severe Gear lube?

Re: Marine Lubrication
 

Hydro,

Can you explain why the synthetic would reduce the oil consumption as stated here ? I can understand the basis for the other noted advantages but the reduction in oil usage is not clear to me at all.

Re: Marine Lubrication
 

Every oil be it conventional or synthetic is "volatile" when heated to extreme temperatures. The higher the flash-point of the product.. the less likely that the oil will decompose and "cook down" and form sludge reducing the oil level in the process.

An oil that is less volatile such as a PAO or Ester based synthetic takes heat better and does not cook down into sludge to nearly the same degree so the level stays normal and you don't usually need to keep adding more oil unless the engine is buring it for some reason.


Does that explanation put it in perspective? :D

Re: Marine Lubrication
 

It not so much as the oil "cooks down" but burns off. Light ends of the oil formula actually get consumed "burn off" because the light ends are more volatile than the heavier ends of the base stock. Synthetics are much, much more temp stable, hence lower oil consumption. Oil consumption is directly related to base stock volatility. The more volatile the basestock the higher the oil consumption. Ken

Re: Marine Lubrication
 

Sounds right.

Re: Marine Lubrication
 

I've greatly appreciated the help I've gotten from this thread. I just got a Blackstone analysis done and I'm interested in your opinions on the comments they provided.

The boat is an '03 Donzi 16 w/Chevy 305 MPI, currently with 165 total hours. The sample I sent was in the motor 35 hours. I used M1 20-50 V-Twin with a NAPA Gold (Wix) filter.

Here's Blackstone's comments:

"The universal averages column shows typical wear from this type of engine after about 256 hours on the oil. This oil was run just 35 hours, so wear could be considered a little high for such a short-run oil. But the metals are properly balanced and we don't necissarily think anything here shows a problem. Silicon could show the need for a new air filter, so we suggest checking that. A clean one might improve wear. Silicon could also be from sealers or an additive, which are harmless. The trace of fuel may be the reason for the slightly low viscosity. It's not a problem."

My only observation is that they may not have taken into consideration that this was 35 hours of marine use. I run my boat mostly between 3500 and 4900 rpms, with little idling. Hell, it's a Donzi!!

I can post the sample numbers if that would help.

Thanks for your input.

Randy

Re: Marine Lubrication
 

gold-n-rod,

I also use the 20/50 V-Twin and Napa Gold filter (1060). Engine is a ZZ502/502. And at this time, I probably have about 30 hrs. on the oil (never have let it go that long, usually do oil & filter at +,- 20 hrs.) Would you please post the address or PM me the address for Blackstone? I'd like to have an analysis done.

Thanks!

Re: Marine Lubrication
 

www.blackstone-labs.com

Be sure to order the extraction pump ($25). It makes it super easy to draw a sample. They instruct you to draw the sample within 30 min of hot shutdown.

Randy

Re: Marine Lubrication
 

Thanks!

Re: Marine Lubrication
 

Please post the results.

Re: Marine Lubrication
 

FYI

The new Mobil-1 Extended Oil Filter is a big improvement over the other in terms of increased retention capacity...much stronger internals and case as well as great filtration. For about $11.00 it is hard to beat.

The main problem with the older version was cases that burst. The new cases can take 5x the pressure.

As I see it this is the oil filter for just about any offshore rig I would use until you get into engines exceeding 700HP and then the Fram Racing seems to be the one used most.

Additionally, the most recent reformulation of Mobil-1 15W-50 extended now has similar additives to V-Twin according to Mobil. That's a stronger base; more anti-corrosion additives and a bit more ZDDP.

I bought a bunch of M-1 15W-50 in quarts at Wally World last week for $6.25/qt.
