The funniest claim I've seen by JTX sellers is that there's no "chemicals" in the oil. Must be made of pure crude oil then!
If you have to ask about cleaning detergents like that, you obviously know nothing about engine oils :hmmmm:
Engine oils are made of base oils, detergents, friction modifiers, heat dissipants, etc. The purpose of engine oil isn't just for "protecting" your engine. It lubricates, dissipates heat, cleans the engine of varnish / sludge / carbon (some extent) and all that. So if your oil has no detergents it's pretty useless. If you don't know what varnish, please go read up about it first.
To me a quality oil is one that keeps my engine clean, keeps my engine cool and keeps it running smoothly without breaking down too quickly.
This isn't called dirty tricks. It's called business. There's no such shop that'll sell brands that they don't carry.
Actually, I'm wondering why you're using such a thick oil.
