Engine oil AMSOIL or Lucas

Amsoil allegedly is the best. I use it in everything and no issues so far.

Amsoil is top tier oil and you can't go wrong with it.

I’m using Amsoil 0w-30 and am very pleased with it. Getting about 1 mpg better gas mileage and had the Amsoil lab analyzed after 3500 miles and numbers are better than what the factory oil showed. All added up, the Amsoil was better at protecting the engine.

My Miata has almost 300k on the original head gasket I started using the far right a few times ago and I don’t leak a lick of oil

I’m not going to argue with anyone about what it does but I’ve used Lucas for a long long time I have a 93 Chevy truck with 400k miles that I have never taken care of correctly I have run it out of oil overheated it overloaded it and abused and mistreated the engine in that truck and its still able to do any thing I need it to.

I use this on my 2003 Passat 1.8T probably every 2-3 oil changes. Motor has 269,000 miles and burns a smidgen of oil on startup. The Lucas seems to help a bit.

Used it for years in high mileage motors. 215,000 on a 1.8 turbo VW

used no oil between 5,000 mile changes.

Ok, so here’s my anecdote: a friend of mine had an old Ranger that had an oil pump failing. He didn’t want to pay me or anyone else to pull the engine and replace the pump so I suggested he just throw a bottle of this in there and see what happens.

Well, his oil light went off and oil pressure improved.

Dominator is a excellent oil

Dominator is great in saws. The only issue is that I'm small saws especially, and at thicker ratios, like more oil than 40:1, some bike oils will not burn completely and will gum up mufflers, screens, piston tops. Mostly high performance racing oils.
