ok, my 01 gs-r is approaching 9,000 miles. wondering if i should change from 5w30 to 10w30??? the last few days its been 95+ degrees out just wondering if i should stay or would there b an advantage to running 10w30? thanks

 

I believe 5w-30 is best for the summer and year round protection. Consulte your owners manual. They will tell you to use 5w-30 year round.

 

depends on how hard you drive the car. If you dont' drive that hard, you can use 5w30. But if you drive or race, you want 10w30 or even 15w50 synthetic mobil1

 

For 5W30, 5W means oil viscosity at cold temperatures (cold oil), and the 30 means viscosity at high temperatures. So an oil that is 5W30 has the same high thermal viscosity protection as the 10W30. The difference is the oil viscosity at cold oil temperatures.

 

Use what it says on the oil cap

 

i use 5w-30

 

and who told you this? 5W30.

 

thanks for the replies guys. i asked this ? cuz i c a lot of teg owners runnin 10W30 even though the manual and oil cap says 5w30. also since its never below 30 degrees here and normally 65+ and summer 85+ i thought maybe run 10W30 but ill stick w/ 5. thanks again

 

i guess i should use "skunk2" instead of 10w30 then?

 

i just changed my oil right now w/ 5w30
