MCT Coconut oil? Advice needed

I have used wvo for years. Mostly in vw transporters, and a Tdi golf, alh. Despite the messes, I do ok with it.

I scored 45 barrels of virgin MCT coconut oil, on the verge of expiry by best before date. All are in sealed barrels. Oil is perfectly clear and the cloud point is just below freezing. Nice stuff.


The oil appears much thinner than the used stuff I get even after filtering.

Does anyone have any concerns about lubrication of the injection pump? I might reduce the amount of heating of the oil in my fuel system to accommodate how thin the oil is, except for winter.

Any advice would be appreciated. Thanks George

I have no experience with this type of oil, but being thicker than diesel, and thinner than regular WVO, it should be fine for the pump.

No experience running it in a diesel, but cooking with it, melts at low temp and it will burn like butter. Also good on pancakes

If it's thicker than diesel you should cut it with gasoline until it has the same viscosity unless you're heating the tank or fuel before the injection pump

Coconut oil has a high amount of saturates and higher molecular weight. Super high cetane stuff. Definitely don't run it in cold temps. Agree to cut it, recommend ULSD and test proportions in samples in the fridge or freezer. Maybe if you know people at the airport you could score the jet fuel that is routinely disposed of when they come out of sumping aircraft and cannot be filled-back for flight use. Beware, though that Jet fuel doesn't have the same limits on sulphur (3,000 ppm vs <10 for ULSD) and the sumped stuff can have lots of water (which is why they check it by sumping), but usually fine from high turnover commercial aircraft, just like high volume stations will have the freshest fuel and least concerns with water.

Hey if you run VWO regularly, I'll say this "fresh" coconut oil will be super nice to run by comparison.

I'm a food scientist by trade, so MCT (medium chain triglycerides) is indeed perfect to run with some pre-heating to thin it out. On the other hand, I have zero experience outside of the pure diesel realm. Do your checks for FFA (pH) and you should be good.

And if nothing else it is a great replacement for butter on grilled corn on the cob
