man just throw in some 0,5,10w30 half synthetic, half mineral, and a dash (like half the recommended amount) of bardahl oil supplement!

that would keep you going for everday driving!!!

if your planning to race/drag the car get 5w30 fully synthetic and a race filter and change the oil afterwards...

the first solution (10w30) gave me the best mileage so far and the engine seems happy...

just me thoughts......... 8)

I may have been a little to conservative with 15-20 years. More like back in the 70's there was an issue with synthetic oil & rubber seals. So the info you found is only about 30 years out of date.
So anyway back to your statement about 0w40 damaging the engine? You're thinking about running 10w40. That's the same viscosity at operating temp but doesn't flow as well when cold. How is that any better :roll:

I totally agree with You E910 :) my lack of info.. and You are right they have same viscosity, only difference is operating temperature. The dangerous now is pouring full synthetic oil to the engine where there was semi-synthetic oil. Same situation with pouring semi-synthetic (or full synthetic) on mineral oil place. Basically if You don't want any trouble with the engine it's the only one way trip.

P.S. info that I have found is dated 2008-12-10
