...just once. Does it blow up? I just have one leftover mahle oc47 that I want to start a rebuilt engine on and run for 20 minutes before I change it and the oil. Looking in it, there looks to be a restrictive valve an inch down. I dunno....
-
It'll PROBABLY be ok for that short of a use at this time of year. Cold weather operation is a much bigger issue as 15w40 on a cold day can get up to 150 PSI at startup pretty easily. But for a 20 minute run on a new build I don't see it being an issue whatsoever.

Seems like the gas o-ring is a little smaller....can't remember. It may spray oil past the top due to the difference (if there is one). The clean-up will give you something to do.
I think the gas oiling systems develop the identical pressures. I have never ruptured a gas filter tin.....yet. And, I have run a lot of 15-40 in gas rigs over the years.
-
Yes, seems to me they all use the same oil pump. I am using the gasser filter flange (this is a cabriolet conversion) as it has the car pressure and oil temp sensors. I need to double check the seat before I make a mess.
-
From what I have read the gas oil filters have a lower burst and bypass rating.
-
I wouldn't be too concerned about the burst rating, odds are the starting oil pressure on one of these still isn't high enough to cause rupture, unless something is woefully defective, but with a lower bypass rating it may simply just send the oil right past the filter without filtration.

Proper filter $5
engine rebuild $1000+
Seems simple to me.
-
The only way it would ruin my engine would be if it grenades and takes me with it. My head will be over it. I have the right filter, just want to use this one up, if I can do it safely.
