Full Synthetic in 2.2 Eco-tech?

We'll it has been a couple months and the engine has been flawless since the full top end rebuild and getting ready to change the oil for the second time and thinking about going full synthetic, my question is, has anyone done it and is there any reason why it is not a good idea?

My ls has used Mobil 1 full synthetic starting with the first oil change and still going strong. 113k on it now, my dad bought it new and it's never been to a shop for an oil change. Nothing has broke besides the a/c. I wouldn't say nothing's broke because the oil but it didn't hurt anything.

Switching to full synthetic did not cause me any problems. Valvoline here.

Why would you think it wouldn't be good for your motor?

If you get synthetic, stick with it. Dont flip flop back between that and conventional.

I think full syn is superior in every way. But no matter what you use, keep it full and change it at interval and you'll be good.

With full synthetic you should be good to 6000 miles (10000Kms) but you should still change the filter after 3000 miles (5000Kms) if you use a conventional filter . Like stratosproject says important for the ecotec to keep oil level as close to the full mark as possible, so check it frequently so you don't starve your timing chain. An other plus for synthetic is that you can depend on the oil life monitor since it is designed and calibrated for synthetic. Also you should buy an oil filter designed for synthetic because regular paper oil filters tend to disintegrate. Synthetic oil filters appear to be more of a fabric material and hold up better.

Here is a picture comparing Purolator synthetic filter on the left which appears to have a white felt like material very soft to the touch, Fram Synthetic in the middle which appears to have a fiberglass type material very rough to the touch and a conventional Fram which is just yellow paper material.

Gah, Fram is worst for GM vehicles...everyone should know that. Use AC delco for oil filters. Alvin Champion lol.

Switching to full synthetic is not a bad idea for a car thats used to regular 5w-30, but never go back and forth, that will cause bearing issues in the future. Nissan and Infiniti cars equipped with the VQ37HR engine block use Ethos oil to prevent corrosion buildup on the intake cam for the VVEL system (intake Cam if you want to call it a cam, its really a solenoid idea from Indy cars). I used approved Dexos synthetic blend oils ATM and never ran accross any issues with AC delco filters.

Questionable about the K&N one out there..dunno what their micron rating is, but you need a good micron rating for filteration.

Shoot, I use the Fram yellow cardboard filters. Got 6k kms on this oil (Castrol Edge w/Syntec) without changing the filter.

Motor's lost two pegs on the dipstick since putting in fresh oil.
