Additive for compressor oil Yong Heng and other brands.

[SDALEX]

Been using Motokote for a long time, cars, boats and yard equipment. Bought my first PCP compressor (yong heng) and I will be adding it to the oil every other change 1oz. Great video to show how well this product works. This is just and FYI of something that might help our "cheap" (according to some) compressors maybe last a bit longer. Yes flashpoint of the product is 60c open air with an ignition source, but the oil we should be using has a flash point of 350-500f+. When mixed with this product it might help a bit on that aluminum connecting rod to steel crank wear.

SD,
Important aspect of high-pressure air compressor oil is flash point, as in, any oil making its way to high pressure piston chamber will ignite, just like a diesel engine, if flash point too low, harming compressor. Many air compressor oils, like HUSKY Full Synthetic and Royal Purple list flash points around 460F, however, specifically for high-pressure air compressors, it's felt an even higher flash point, such as 520F from SecoLube 500 Synthetic, and others, is a safer bet. Not sure any additive, with a low flash point, is a good thing. WM

Just finished a 10 cycle 7 minute each run for break in. No explosions. I'll pull the head and see what it looks like inside, doubt I will see any carbon. If I do I will definitely post a picture. Broke a engine case on a Volkswagen out in the desert. Was able to drive it back about 5 mi with no oil. That is what sold me on the product many years ago. Also running very diluted about 5%.

WM, I was curious about the same thing as the flash point in the video was described as "greater than 200 degrees" (F). Pretty ambiguous description!
I'm about to rebuild my YH & the reduced friction factor of Motorkote is appealing if it's SAFE!

Shouldn't be any explosions, with the % that I'm using or even in greater concentration because we are missing 1 primary item to make fire- the ignition source. Diesels have glow plugs to help start the process. You have to have an ignition source to make things explode with combustable material. I like to barbecue alot and havnt blown up yet! Beef fat has a flash point of 400f.

Gerry,
Ambiguous, without a doubt, even presenter felt same, never heard of a friction problem with YH, have heard about dieseling. Do what you think is best, not for me, though. WM

Diesels have glow plugs they stay glowing red hot even after start up. You have to have an ignition source to make things explode with combustable material.

SD,
Don't agree on ignition source needed for diesel engine, high compression of fuel causes detonation, glow plugs help in starting, not part of normal operation. In any case, just pointing out potential concerns, each must decide what's best for them. WM

100% correct do as you please. Yes diesels use compression ignition but they need the fuel ignition source to start the whole process to create the heat to keep it going. Can't make fire without 3 things right? Only reason I'm going to use it is because everything I see online is broken connecting rods and metal fatigue failure this will help with those situations.

SD,
I wish you well. WM

Forgot to add which oil I was using- Sullube compressor oil recommended by local compressor company 505f flash point. SDS http://www.sullairinfo.com/Downloads/Sullube_MSDS_English.pdf
