Vegetable-Based Motor Oil?


I am planning to run my '83 300D on biodiesel and WVO and was wondering if anyone has heard of a vegetable-based diesel-rated motor oil that is commercially available?

The only site I was able to find is pretty ghetto looking but they do have products with "D" in the their names. No idea if they are actually selling the stuff to consumers directly.

I would go with the conventional stuff or let someone else try it first.

Any takers?

All Castrol products are veggie based (Caster Bean) aren't they?

If you'tr trying to get away from using petroleum products altogether, I think that you can use any synthetic oil and meet your goal. Not 100% sure, though...

Those oils are made by the major petroleum companies.

Here is a pretty good article about synthetics..

This is the way I understand it. I am not a chemist. I don't make oil, dino or synthetic for a living.

There is a major difference in 'dino' and 'synthetic'.

Dino oil is taken from the ground and 'cracked' essentially cooked and broken into smaller hydrocarbon chains then its sorted. Thus different types of things are made from crude oil.
Gas, motor oil, diesel fuel, etc.

Synthetic oil is engineered from the same types of materials. However, instead of being a major jumble of different sized hydrocarbon chains, synthetic hydrocarbon chains are made all the same. Thus making a lubricant that is made up of all the same sized hydrocarbon molecules. I imagine that the source of the hydrocarbons used to make synthetics varries quite a bit.
