Mobil 10w30 vs. 10w40?

Oil obviously will not help with the injectors cycling...but they do make a lot of noise...which is normal. Love the sewing machine sounds!!

yes, I thought MY CAR was special.

Viper. Sewing machine, vacuum cleaner, clownshoe? I'm so confused!

anyone know if Walmart carries the 10 40? in Canada? Could not find it anywhere else yet.

Tator gave me the option of 10w-30, 0w-40 or 15w-50 two years ago. 15w-50 was overkill for me back then but standard now since I did my heads/cam work.

done all three on my gts, no issues......
