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.

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.
