Should I use Dow 33 or Dow 55 on my paintball gun? This has been a very common question since the Bob Long Intimidator’s and Smart Parts Impulse has been out. These guns were the first guns to use Dow 33 as a lubricant as opposed to normal paintball gun oil (which is also synthetic) They needed to use a heaver weight lube that didn’t burn up as quickly as oil during the high rates of fire the guns can achieve. Some where along the line some genius said hey I’m using Dow 33 now Dow 55 must be better. So that’s how this question began.

Dow 55 and Dow 33 both have similar properties, however as stated on Dow’s web site, Dow 55 can swell orings slightly. The fact of the matter is you should follow your guns manual.
