Thanks for the replies Kent, I guess I was more curious as to the weight of the oil you used. You go for the full on "Le Mans" 20w-60?

No, 15W-50 in the summer, 10W-40 in the winter months.

$10-11 per quart :shocking:

They don't list the pricing for the 20w50, odd.

Plus shipping, and from what I gathered in that oil thread the shipping added around 20% to the cost!

For those who didn't read all 42 pages, it looks like Renewable's "HD" oils have the fuel dilution improvements developed for that guy's Audi direct-injection V8.

Both from a Mobil site:


Will the use of Mobil 1 void my new-car warranty?

With the exception of the Mazda rotary engine (Mazda does not recommend any synthetic oils), Mobil 1 will not void new-car warranties. Mobil 1 exceeds the API and ILSAC engine-oil service requirements of all new-car manufacturers, both import and domestic. If in doubt, always check your vehicle owner’s manual or contact your vehicle’s manufacturer.

Question:
Using Mobil 1 in a Mazda Rotary Engine
I have a 2005 Mazda RX-8. This has a rotary engine, which injects oil into its intake path. Can I use Mobil 1 without risk of incomplete oil burn and or buildup?

Answer:
Mazda does not recommend the use of synthetic oils in its rotary engines. To help maintain your vehicle's warranty coverage, we suggest that you follow your car builder's engine oil recommendation.

10w-60!! Damn

GoodfellaFD3S 01-28-08 10:51 PM

The 'synthetic oil being detrimental to rotaries' thing is ridiculous.

Synthetic Idemitsu was formulated specifically for use in......you guessed it, rotaries.

I've torn down many many motors, and the ones run primarily on synthetic showed less wear.

so after all , the Mobile 10w 30 synthetic oil will be the best oil for Rotaries? i thought the castrol GTX 20w 50 is the best oil for rotaries

No.

The discussion of fuel dilution though has me most interested.

OMG another what type of oil thread. try K-Y.

pietrino 01-30-08 02:54 PM

i use Royal Purple 10w40

mikeric 01-30-08 05:45 PM

Great article. Now I know to use 0w-XX weight in synthetic, the only question is what is the second number we should be running? I'm assuming 30-40.

Which ever one yields 50psi @ 3000rpm.

I used to use RP 10w30. I'm using 15w40 now. Once i get my heat exchangers in order i might drop back to 10w30 depending on how everything works out.

money 01-30-08 10:24 PM
