Joe Gibbs Racing oil?
 

OK guys, what does anyone know about this oil. It has a lot of hard core race teams (not marine that I know of) using it.

They claim to have huge ZDDP content and formulate it (ZDDP) based on your operating temps among other things such as RPM, HP big or small block and type of racing. These are not formulated for street use.

Any opinions out there for Marine use?

XP 6 is wnat I am looking at due to temperatures formulated for.

Very expensive BTW :eek:

It does have a good slug of zinc and it wll work in your marine engine.

Ken

I just remembered that it is advertised as a low phosphors oil, so it probably is not the best choice to use for maximum wear protection?

There are low zddp products...from Lubrizol and others that are very effective at lower doses.

The oils cost more and usually you can't tell from a label what's in it...

just and fyi..

Offsore boats are safe with Redline...M-1 and Amsoil motorcycle oils as they are high ZDDP oils.

Hydro,

Any comment on the Gibbs XP6? I read many pages back that it too is Lubrizol product but with high levels of Zinc.

Their claim of being formulated specifically for 280 degree temps is what piqued my interest. :eek:

.

Gibbs makes good stuff....wow a Lubrizol product with ZDDP.

Meaning........? :party-smiley-004: Are they considered mutually exclusive?

Has the Amsoil Series 2000 20W-50 racing oil been replaced with the Amsoil Dominator 15W-50 racing oil? I can't seem to find the series 2000 on the site anymore, so I ordered the Dominator. Any insight Hydrocruiser?

Yes, it has. The new Dominator 15w-50 is the latest and greatest!

SAE 20W-50 Synthetic Premium Protection Motor Oil Product Code: AROQT-EA

20W-50 Advanced Synthetic Motorcycle Oil Product Code: MCVQT-EA

Dominator 15W-50 Racing Oil Product Code: RD50QT-EA
AMSOIL Dominator Synthetic Racing Oil features an additive package heavily fortified with zinc and phosphorus for superior long-term wear protection

SAE 15W-40 Heavy-Duty Diesel and Marine Motor Oil Product Code: AMEQT-EA

All four Amsoil products would be fine.

Dominator 15W-50 Racing Oil Product Code: RD50QT-EA
AMSOIL Dominator Synthetic Racing Oil features an additive package heavily fortified with zinc and phosphorus for superior long-term wear protection

So does the ARO, 20w-50

All high in ZDP for anti-wear and anti-corrosion.

Fewer oils these days are true GRP IV. PAO Synthetics. But these all are.

Any of these along with M-1 V-Twin and M-1 15W-50 SilverCap are great choices.

mobil1 v-twin sale
 

advance auto parts site. mobil1 v-twin 20w-50 7.99/qt. at check out enter promo code PS20 for additional 20% off. that's $6.39/qt. and free ship over $75.00.

That is a great price.

I was asked to do a brief 2010 lubrication recommendation.

#1. Do not use SM rated oils as they have too little ZDDP. Mobil-1 20W-50 V-Twin is still the one to beat. Royal Purple, Amsoil V-Twin and Redline 20W-50 are amazing as well.

$2.Use a Wix oil filter or Mercury racing oil filter and you will have the best combination.

#3. Mercury 20W-40 Synthetic Blend is an outstanding oil!

#4. If you run hard change often. Synthetic in a boat engine is not for extended drains...it's for better heat protection and extendedbearing life.

#5. Castrol/Kendall/Valvoline SL rated oils 20W-50 are excellent.

Do you still like 15-50 Silver cap M1? It is so cheap in the 5qt bottles at walmart it is hard to avoid.

Hydro - any downside to running Valvoline 40 Racing conventional oil? 540's NA, temp never above 180. Engine builder wants to stay with this oil. Using a Wix filter. Thanks.

I was wondering if someone could shed some light on the FC-W rated oil.

When I read about oil in our Merc 4986HO Manual they have a note "....., non FC-W rated synthetic oils,.... are specifically not recommended."

What is FC-W rated oil? What does it do?

It seems only Mercury/Quicksilver oil has this rating. A little confused as to why.

Thanks for the help. :coolcowboy:

HydroCruiser -

Any opinions of the Brad Penn 20W-50? A couple of engine builders in the area swear by the stuff, and is currently what I am running.

It's an NMMA certification for oils. Happy reading: http://www.nmma.org/certification/lo...nual_9-06_.pdf

Amsoil Marine has an FC-W rating, maybe others as well. Mercury doesn't have a monopoly on that market.

Thanks for the link. :coolcowboy:

Did you mean the Merc. 25W-40 Synthetic Blend?, because I think they have a 20W-40 full Synthetic now.

Gotta love the #1 procedure:
Anybody familiar with oil testing see anything different than automotive lubricants? Well, besides the salt fog and Yamaha 115hp performance test.

Anyone know of the best/cheapest place to buy Mobil-1 V-twin? The wal-marts that I have checked do not carry it. thanks

What info is available about lower unit drive lube oils?

Hydrocruiser, what do you think about the Amsoil/Donaldson oil filters compared to Wix and Merc Racing filters?

Hello all!

I received several PM's to continue the Marine Lubrication Thread in light of the many changes (good and not so good in the oil industry) for marine engines lately.


Perhaps a good place to begin is to make mention of what a Marine Offshore Oil ought to be:

-The right viscosity for the climate and type of service for lubrication on startup and full operating temperature.

-A high potency detergency additive package to prevent sludge.

-Anti-wear additives to cope with the high shearing forces when using engines at or near maximum RPM.

-Perhaps the single factor that seperates a true marine oil from an automotive oil is that a good marine oil needs to address the additional amount of moisture/condensation present in significant amounts in engines exposed to this type of environment and set up with wet exhaust and the potential for some reversion as well. Leave an engine sit around for a year in a boat yard and wonder why it won't start and maybe needs to be rebuilt? Corrosion.

-Forget extending oil changes in the marine envoronment and this especially goes for super-charged engines subject to fuel dilution.

That should be a refresher for what the "tall order" for an Offshore Engine Oil.

To be continued. :)

Good Choice??
 

I have been running Amsoil 15W40 Diesel and Marine oil in my mild modified 350hp 355cu for the past 7 years and have no issues. Is this a good choice or is there a better one??
This is along with the new Amsoil EA filter. Just think the high TBN is good for the winter storage.

That is a great choice!

Amsoil 15W-40 Diesel and marine has a very stout detergent package as it can handle soot in a diesel engine. It can be used in gasoline engines too.

This oil has specific additives to prevent corrosion that occurs from condensation when an engine sits out in the boat yard. Amsoil buys their base stok synthetic oil from Mobil and their "better oils" are Group Iv. as this one is.

The Amsoil EaO oil filter is made by Donaldson and has a heavy case that withstands high pressure very well and it is amoung the best in particulate filtration.

I feel this is a great oil for engines up to 454 cubes that are not heavilly modified. Bigger engines shear oils down and you might be better advised to use a 20W-50 Synthetic.

Have any of you oil gurus done a test on Neo motor oils? I was specifically considering the P40 conventional oil. Currently using Valvoline 40w.

High TBN numbers have nothing to do with storage.

It is a number on a scale that is used to deal with acid neutralization from combustion in diesel engines.

The acid was formed due to the sulfer in the fuel, but due to low sulfer diesel fuel now, this number is not as important as it was 15 years ago.

If your hanging your hat on a TBN number, times have changed.

Ken

True, TBN has little effect in storage.

But TBN is applicable to gasoline engines, as both sulfuric, nitric and organic acids are formed from combustion gases and water - in any internal combustion engine. It is true that the previous higher sulfer content created more acid, but the issue has not gone away. That is why "extended change" oils have higher TBN to start.

I agre the issue has not gone away, but with low sulfer fuels, both gas and diesel, it is much less of an issue.

Besides, when you store you engine, you should have fresh oil in it and there should be almost no contamination in it.

Yes "extended change" oils have a higher TBN, but does anybody really change the oils at the extended interval?

I would guess the majority of the people on ths board would say no.

Ken

Disagree
 

High TBN is going increase the amount of additive the oil has left to neutralize acids. When your boat is stored the oil sits on the engines bearings and this is were excessive acids can take a toll on the bearings surfaces. The high TBN is insurance that over time the additive content level is still high enough for proper acid/soot control.

Acid neutralization also takes place in gasoline engines.

Amsoil 15W40 Marine Diesel has a high TBN number of 12 which is even higher than most synthetic oils which are usually around 9. This high TBN gives this oil a higher drain interval. This gives the oil a longer acid fight control within the motor.

I don't were hats.:drink:

I guess you didn't read my last post.

Ken

That's exactly what I was thinking!!!:lolhit:

Anyone try the Amsoil Z-Rod 20-50 yet? Advertised for long lay ups with more antioxidants and corrosion inhibitors. Not sure if it's a class IV synthetic?

Valveoline Racing Synthetic 20w-50?
 

Anyone use it? Comments? I see my local Autozone stocks it.

Resurrecting the Dragon - the world's longest oil thread
 

What an incredible thread! All these years boating (about 30) I've used manufacturer recommendations only and I see a lot of other possibilities now!

Not that manuf recs are necessarily bad. Lets start with Mercury. How many Mercury oils are there?

At least three...
1 Original 25W-40
2 Blended semi synthethic 25W-40
3 Full synthetic 20W-40

Which one would be the best for 500/525EFI engines? I heard the most recent full synthetic Mercury oil has less antiwear additives (Zn, P) because of catalytic converter issues. Well, most of us don't have cats and want the best oil.

What about AMSoil Dominator 15W-50, Bob Teague's current racing choice? He runs 525's. They change oil after every race. Can you use this for 20-25 hours for average to hard recreational use?

Thanks, Andy
