I noticed on the Valvoline website that they have an engine oil specifically for Compressed Natural Gas, Liquid Petroleum Gas, and Propane. There is nothing special in their PDS http://www.valvoline.com/pdf/premium_blue_geo.pdf What makes this oil different (besides marketing)?

Valvoline’s Premium Blue® GEO meets the "Natural Gas Engine Oil – CES 20074 Cummins Specification"

http://www.cumminswestport.com/pdf/technical_bulletins/2009-05_Natural_Gas_Engine_Oil.pdf

"Do not use diesel engine oil in a natural gas engine. If diesel engine oil is used, valve torching, piston scuffing, and reduction in spark plug life will occur."

Take a look at the ash content.

Propane produces a lot of water. Would the reduction in sulfated ash reduce the formation of acids?

Burning gasoline in an engine produces a lot of water.

Some of the oils marketed towards LPG and so forth have lower TBN, too. These fuels eliminate the problem of fuel dilution, among other things.

IIRC those engines combustion burn hotter and require different ash levels?

That might be part of the issue, too, 3311. However, when running a propane taxi fleet, I never bothered with any CNG/LPG/Propane oils. It was simple Quaker State conventional 10w-30 at 6,000 mile OCIs.

The biggest issue on propane at the time was the same as the introduction of unleaded gas. Hardened valves of the time weren't as "hard" as they should be, and in the early years, didn't stand up as well as they should have, whether on unleaded or on propane. Heat might have been a bit of an issue, but there certainly was no problem with carbon deposits.

I think Dino FS is suitable for propane as well.

Gas engine oils are formulated for low or no ash. Ash deposits in the combustion chambers form over time and lead to detonation or preignition in high-BMEP gas engines. Since most gaseous fuels have no sulfur, high TBN is not needed, so the oils can be formulated to produce no or very little ash. The main problem with converting gasoline engines to run on propane or natural gas is intake valve seat wear due to "dry" conditions in the intake system. Hard valve seats are required; materials such as Stellite or Triballoy are popular in such applications.

Also, the mention about not using diesel oil in an LPG/CNG engine is a bit odd, and certainly has no context. I would certainly advise against using a diesel only engine oil in a sparker. Do they mean not to use the latest diesel specs? When was the quote written?

Back in the day, most PCMOs had a diesel specification as well, and were used without issues in propane engines.
