Those who use motor oil for lube...

Anyone tried Quaker State Q (Full Synthetic)?

I would wager that diesel oils are the best as they contain the most detergents. Something like Rotella T synthetic would be optimum.

Thats an interesting point! I've been wanting to try out diesel oil for that reason. I have found that mobil 1 works better then CLP but to be honest I've never tried diesel oil. Ill try it out at the machine gun shoot in a few weeks at the impact zone here in houston.

All I know is that running Shell Rotella T in my old LT1 Trans Am sure cleaned it out! The guy had run GTX before and the Rotella had to be changed every could hundred miles for the first 1500 or so miles. Each time the filter was full of pudding consistancy sludge. It's a wonder I didn't stop up the oil pickup tube screen.

Works good for me.

I'm about 1/2 way through a quart bottle purchased in the late 1990s.

Apart from that, I will use TW25B or other lightweight grease when grease is needed.

I know "why" questions make people defensive and all, but why do we need detergent oil in a rifle?

Same reason it's in there for the engine, to help with deposits. Consider it to be the same as the "c" in CLP.

FWIW I have used the Rotella T synthetic as gun oil before and it works just fine. The only problem with it is the smell for ccw guns. Currentley using 95% Mobile 1 5W 30 with 5% STP and it is a great lube for AR's and pistols.

Don't laugh... but I use Walmart pure synthetic. It's low cost and seems to be holding up pretty well on the guns I've been shooting. The one thing I noticed about synthetic versus CLP is I lube up a gun, put it in the vault and a month later its still wet. CLP dries out between cleanings fairly quick.

Here is the IZ we are limited in regards to gun oil, except for what we can order from home. The PX only stocks WD40, but also has STP oil treatment for some odd reason. Anyone have experience with using this STP?
