M1 20W 50 V-Twin Synthetic Oil As Gun Lube ?

[ChrisD46]

Does the above M1 20W 50 sythetic oil contain any chlorinated esters ? Apparently there is quite a discussion / concern over gun oils (such as Militec - 1) which contain the dreaded chlorinated esters know for causing corrosion stress cracks in metal (mainly AR bolts) . The M1 20W 50 V-Twin oil gets a lot of love as a gun lube - I would love to try it if it is safe as a slide / barrel lube !

Why do you believe you need a 20w-50 (as in viscosity -- not questioning engine oil for a firearm)?

I've used several lubes over the years including some heavier weight M1 lubes. They work fine for me. It's really hard to go wrong with just about any decent syn gun lube including motor oils. FWIW my fav is Shooter's Choice FP-10.

A previous google search indicated the M1 20W 50 V-Twin Synthetic ,M1 0W30 and 0W 40 oils had key charecteristics (i.e. temp range , flash point , viscosity , etc.) that were deemed very desirable for a gun lube ...I don't want to debate whether or not a synthetic car oil is appropriate for use on weapons - only interested in my original question : " Does M1 20W 50 V-Twin Synthetic Oil contain any chlorinated esters " ? ...If no one here has experience with this topic I will contact Mobil however not sure they will actually answer the question ...

Will my gun fall apart if I use 0w-30?

V-twin oil only works on double barreled shotguns .....

I thought most people didn't like Militec-1 because it sucks as a lube and a protectant, not because of cracks. I admit I fell for the Militec-1 hype. And that's all it is - hype. The stuff I got would get sticky after a month or so in the safe, and burned off to quickly when used on an AR bolt.

A quick google search for chlorinated esters shows most people are parroting a post from Grant Cunningham's website. I didn't see much else besides that.

As for your M1 question, I don't know. However, considering M1 spends its life in metallic environment (oil pan, crank, valves, pistons, etc.), if the oil itself was significantly corrosive to metal, I doubt XOM never would have brought it to market.

I'm not a chemist or metallurgist, so I could be very wrong. Hopefully someone can correct me.
