With ester base stocks and a high HTHS for the grade, RL 0W-20 or 300V 0W-20 will very likely maintain both their kinematic and HTHS viscosities over the interval better than many off the shelf xW-30's which are designed for fuel economy. Some xW-30's have shown to shear to a 20 grade in as little as 1,500 miles in uoa's.

Sorry, a bit OT there.

Wouldn't running 300V 0W-30 or other high quality oils be the best compromise? You get the low viscosity level of 0W, but the 30 weight won't shear to 20 weight as quickly. Subaru recommends using higher weight oil under harsh conditions.

There is no 300V 0W-30, only 0W-20 and 5W-30.

300V is excellent oil, but for info, it has not been submitted to the API or ILSAC for certfication for those that want to run a "certified" oil. 300V 5W-30 would be overkill for most applications here. It has a high HTHS of 3.5 and will behave similar to a 40 grade oil.

There are some uoa's here on tracked and street driven 300V 0W-20 and Red Line 0W-20. Some in forced induction and raced applications. There are also uoa's here on tracked cars running regular Subaru 0W-20. Motul 8100 0W-20 would work well for most applications and 300V 0W-20 is for those that need/want high ZDDP, high molydenum, high High Temp High Shear, and tri ester base stocks.

If you have a built engine then 300V 5W-30 or 0W-40. The high HTHS of 300V 5W-30 means that it will likely have oil pressure comparable to some 40 grade oils.

sry the late reply, I live in arizona like bluesubie said.

we have speced out the FA20 and there is a good reason they say 0-20w. The clearances are very tight and we would recommend running a quality synthetic oil over a thinker weight.

What if the car is turbocharged and easily exceeds past 100c? Would you recommend I switch to a 5w30 grade oil. I've been running Toyota's 0w20 for the first 4k miles and then switched to motuls 8100 x clean 5w30 for the next 3k miles.

That should be fine in a turbocharged car. Although most GF5 5W30's shear to a 20 grade with hard use, X-clean meets ACEA C3 specs so it has a high HTHS and thick 30 grade viscosity when hot (it's nearly a 40 grade). As shown in WRX uoa's, X-clean typically stays in grade under hard use. If you want to go a little lighter next time, Motul Eco-nergy is a thinner 30 grade.

FWIW, Subaru Japan allows 5W40 in the BRZ in severe conditions.

So what you are telling me is that it's basically a 40 grade? My cars only pushing 250whp and 200tq. Should I be concerned?

5w30 is fine especially if you are in a warm climate.]

If you have not already seen it watch this video and look at the oil temp vs pressure vs oil weight data
http://www.ft86club.com/forums/showp...&postcount=305


look at you oil temps if your getting over 235 then you need an oil cooler or a better oil cooler or you need to go to a thicker oil.
an oil cooler air\oil type will drop a few psi oil pressure due passage of oil through cooler.

Australian and south africian dealer now putting in 5w30 or 10w30 at standard service.

if you have forced induction you should have an oil cooler and be running at least 5w30 10w30 or even 10w40 depending on climate\season unless you live in iceland and drive so sedatly your oil never gets over 230 f

Modern synthetic oils wont break down till mabe 300F but its the oil pressure drop as the oil thins out due high temps you need to be concerned about. The viscosty rating is usually quoted at 100C\212F so as it heats past that its getting thinner than the rated viscosity

I can get my NA car on E85, oil temp to 240+ F on track and i dont push it that hard on a warm day and easily 230 on a monutain run before oil cooler install I run 5w30 or 10w30 NA

Yes, think of X-clean as a very thick 30 weight, but no I wouldn't be concerned given the forced induction and the temps.

The HTHS is 3.5 in order to meet European specs (similar to some light 40 weights) and the viscosity at 100C/212 is 12.0 which is thicker than Eco-nergy and any off the shelf GF5 oil.
