What is it? is it a new oil on the market? i went to change my oil yesterday, bought all the stuff, and it said gf-3 5w30 was needed.....

i proceeded to change the oil with full synthetic 5w30 stuff that i have always used. Am i going to have any problems? or should i find some of this gf-3 oil and and switch it out?

i did a search and didnt find anything.

Thanks alot.

GF-3 is old news. GF-4 is current.
