What viscosity grade motor oil do you use?

 

bump(p.s. wc_one believes 10w-30 ruins our engines!)

 

I know ... I'm such an idiot for following the manufacturer's recommendations on oil viscosity . I'll go tell my friend he's using the wrong oil (10W 30) in his '89 Civic that has 345,000+ miles on the engine!

 

wc_one......So tell everyone what U think of 10W30? Please give us first hand experience on your experience with 10W30 oil in the S2000..

Please explain to us why 10W30 will Damage our engines?

What's the point? You'll just question everything I say anyway. Do some research and learn it for yourself first hand. Then you'll know for sure that I am right.

BTW stop quoting me out of context. I said hot weather and high RPM driving. High rpm driving is 7+k sustained rpm.

10W30 like the manufacturer recommends...if they can build a motor to spin to 9K rpm, I think they would know which oil it needs, so I will stick with the good engineer's @ Honda recommendation.

 

I really worried about the person that puts in 20W-50. And just mildly worried about the people that put 10W-40 in their's.

 

I use 0w-5 in everything I have. Done it for 15 years and no oil consumption or oil related failures. So, Dario, don't worry.

 

I've used 5w-30 and 10w-30 in mine, no issues at all. anything heavier and its just not slick enough for this engine and will break down very quickly (the oil, not the motor).
