    I have been playing with the idea of trying out Mobil 1 Synthetic on my guns. I have read alot of posts of people using it but they never say what weight they use. If you use Mobil 1 what weight do you use and why?

    Thanks for the help.

    15w50 or 10w40hm is what I use.

    Whatever my friend put in his truck at the last oil change. I drained a couple of ounces out of the gallon jug and that will last a long time on my guns. I was also given some refrigeration oil at the garage, that looks like a nice fine light oil.

    You don't need to buy mobil 1. You do not need to use synthetic. All motor oils will outperform any gun oil, unless you plan to travel to Antartica. If your car will work in your climate, so will your gun. All gun lubes are a ripoff, don't believe the hype.

    Use what is leftover, drained from your oil bottles on your next oil change-- you will have enough to last a lifetime from one oil change leftover. Last time I changed my oil, I had over 50 ml. that drained from the oil bottles afterward.

    Heck, you can use peanutbutter or Crisco in non heat-sensitive lubrication applications. A particular lubricant needn't be intended for extreme conditions & doesn't need a very long service life in most firearm applications.

    In situations where you go to the range, work the gun for a few hundred rounds, come home & clean off all the lube, relube and repeat the use cycle every weekend or so, your lubricant has an in-service life cycle of just a few hours.

    On the other hand, if you're out on the loose, chasing badguys thru dusty/frozen/wet/hot-dry climate for an extended period & are a continent away from a maintenance facility, then you may actually need some kind of heat-proof, high shear strength, long chain super-duper long-lasting gee-whiz lubricant.

    And it is good to use on the locks as well!

    If it is made for guns, USE IT! That's the word form the Armorers course.

    10w-30w. 1911s, 22lr semi autos, rifles. A quart last a LONG time. I put it in an old eye drop bottle.

    I just don't care for the smell of motor oil on my guns.

    Synthetics have a higher coking point than conventional oils, and that's their main advantage. Yes, a higher max operating temp does make a difference in a gun application.

    Lighter weights are intended to balance off the lubrication against engine drag, so they aren't necessary for a gun that isn't cycling 3000 times per minute. Race oil is heavier because it's intended to not thin out even when very hot. That's why I bought a quart of Royal Purple to use as gun oil.

    On the frame rails I use lithium grease.

    Mobil 1 is so overengineered compared to the conditions of a gun that it's irrelevant.

    The temperatures, pressures, and cycles are far far lower than those inside an engine. The tolerances are much higher, but this is partially canceled out by the fact that you're a good hundred+ degrees below the oil's operating temperature, making it much higher viscosity.

    The minute differences in various Mobil 1 weights aren't going to make a difference using it as a gun lube.

    About as bad as gun lube debate, is a motor oil debate...

    Mobile1
    Amsoil
    Redline
    Castrol
    Valvoline
    Royal Purple
    Generic Wally mart
    Dollar store brand
    Blah blah blah...... You are over qualifying the lube.

    There will be no functional difference. If you are paying for lube for your gun, you are a sucker, shill, stooge, etc...

    Maybe if you are running the hell out of an M2 Browning I could maybe agree . Otherwise , your run of the mill G19 isn't going to realize the benefit of Royal Purple , Mobil 1 , etc.

    Just changed out the Road King's juice yesterday.

    I keep some 20W50 in a needle oiler bottle for my firearms.
