how do you know if your G is a rev up or non rev up

If you have an 05+ 6MT then you have a rev-up engine...

Do you mean strictly 05, or do you mean 05 models and above?

05 and up that have a 6mt

05+ means 05 and above.

if you have an automatic you dont have a revup.

if you hhave a 6mt that is a 2003 or 2004 you dont have a revup.

anything else, you have a rev up.

You'll know if it's a revup because you'll be burning 3 quarts of oil every 3k miles...

hey i have a rev-up and my oil is fine... Thank you
