After half a year running 5W30 on my 530HP Mopar 440 I was wondering if I shouldn't change to an oil like 10W60. I was told many times to do because they told me a 5W30 doesn't have such a film strength like a thicker oil.
What's this all about.. what happens if I race that car and the engine oil gets really hot (270F for example), a 5W30 will be to think to have a protective film OR WHAT protects my engine? When reading AEHaas his text you could think that as long my high volume oil pump can flow and keep the pressure I could even go up to 300F right? Or when do you say "I need a thicker oil"?
Will a 10W60 at 270F have more film strength than a 10W30 just because it it's thicker?
any comments on this?
