Was looking at Volvo VDS 5 (reduced HTHS) oils safety data sheets, most of them seems to contain coconut oil, why is that ? Only Shell and Mobil VDS 5 doesnt have that but they seem to be GTL base oil.

I use coconut oil in my bar and chain oil (and bicycle chain oil) It makes it vey tacky at low and normal temperatures but becomes fluid and thin when heated up a bit. very polar stuff too.
 
Bought a big jar of coconut oil at Costco couple months ago for cooking.

Glad I found a new use for it! Can finally finish the oil before it spoils.

Coconut oil, reaction products with boric acid. Seems to be common in many 5W30 oils. But why is it not used in those VDS-5 oils that are GTL base ?

Most Vegetable Oils (VO) are transesterified into functional esters, including coconut oils.

See this paper, Section 3., Transesterification

Chemically Modifying Vegetable Oils to Prepare Green Lubricants, https://www.mdpi.com/journal/lubricants

"...Vegetable oils used directly as base stocks or lubricant additives cannot perform satisfactorily. They have lower thermo-oxidative stability, higher viscosity, and lower volatility. They burn incompletely and form deposits... Therefore, before using vegetable oils as biofuel/biolubricants, they must be chemically modified. This can be performed in two different ways:..."

Coconut oil is somewhat of a universal lube in south India (where there are a lot of coconut palms all along a very long coastline, so..) for such applications, or to lube a squeaky door hinge, that sort of thing. The weather out here is tropical hot (texas gulf coast / florida weather) so it doesn't ever become tacky and solid unless you refrigerate it.
