has anyone used this oil ? I have and can see no differance. on 4,000 miles runs the same and hasn't used any.

 

most likely the average person wouldnt...oil is pretty much oil nowadays except for how long you can go between changes. I tend to run particular oils because they offer the correct wt numbers for what i want and I prefer syn oil.Its all about preference..

 

no, I haven't. I'm kinda brand loyal to what I like.

 

From what I've read about it in assorted magazine articles and engineering blogs etc., it seems like the real deal, but that being said....I'll just stick with Mobil 1.

 

There was just another thread on that oil not long ago. Here it is, https://www.chevyhhr.net/forums/maintenance-upkeep-50/new-oil-39364/

If you look at the web site for the manufacturer of g oil they don't list it as meeting the minimum requirements for our engines, at least not the last time I looked.

 

If they want people to use it and it is supposedly just as good then they should make it less expensive than conventional oil not the same price.

 

it is syn. oil 5-30 first oil change with coupon free rebate came back with coupon for 20.00 off next 5 qts.that 2 oil changes for 5.00 .it smells different than reg. oil
