oil additives...

[GoLions95Burban]

Folks,
coming up on my 2nd oil change for the ol suburban and was contemplating using oil additives. Yes/No/Maybe so? any particular product ya'll like? thanks in advance!

For the 6.5, I went with what came in the lube's bottle and did not mess with mixing additional stuff in.

Might consider watching trends from oil analysis to better frame how often to change the oil as a first step.

I installed an engine oil bypass filter in all of our 6.5s.
Either FS2500 or Amsoil.
300,000 plus miles per vehicle

installing a provent 200 crankcase breather and eliminating the CDR will help if there is any blow by. it will catch any oil coming from the crankcase and keep if from going into the turbo or at least help better than the CDR will. setup a drain back hose into the block somewhere or leave the hose so you can drain it every so oftin and pour it back into the engine reducing oil consumption. Amazon sells a knock off version that comes with a wire mesh filter. toss that in file 13 and buy the real replacement filter for it.


the only oil additive that would help any if there is low compression is Restore. it has some additive like copper and what not that is supposed to stick to the cylinder walls and fill in scratches helping with a weak cylinder and blow by, but if you do any oil analysis this stuff will set off the red alert with the analysis. reading will go off the charts for metals in the oil.

Seeing as the topic of filtration came up.

If the Burb has 4WD and still has the filter in its OE location, definitely get a remote filter kit. Am not sure what mind altering substance the GM engineers did the day they finalized that design. Nastiest and worst oil changes I ever experienced.

Installed a remote filter and life was back to normal.

Where did you mount the ProVent?

Where did you mount the ProVent?

I have not tackled that task. I was thinking about using the space where I installed the remote fuel filter right up on the firewall where the trans dipstick tube is. others have used the fan shroud face on the passenger side so the drain hose is up front easy to get to.

I use a brand of stuff called Liqui-Moly.
It is a product that adds and builds platelet to bearing surfaces.
Nasty black looking stuff. I dont know what it will do to an oil sample thats sent in for testing but I’m about to find out, I think.
I sent off an oil sample to Black Stone about a week or two ago, results have not yet came back in.
This is the first sample on this engine, 266,000 miles on it.
