can i mix %w-30 oil with 10w-30 and run fine? will it hurt the car?

fucking thing i fixed all the leaks and shit. now i got another one from the oil pan gasket being shit. fucking car. i have almost had it, im bout to say fuck boost and drop the h23vtec in now and go all motor.

yes you can mix 5w-30 with 10w-30 and it'll run just fine... I've never mixed oils in a car but have in lawn equipment and it never hurt anything.

yeah, they're multi viscosity oils, the first number is the viscosity when cold, the second number is the viscosity when hot. So when they're warm they'll be the same viscosity. Basically, it'll keep your car from eating itself.

yeah it's fine if you mix it.

just mix it and get 7.5w-30 :D

actually the first number is the weight of the oil and the second is the viscosity if i am not mistaken
