Engine oil Mannol or Lucas

Been using Mannol 5w30 Full Synthetic for past 35k miles now without any issues.

For the UK, cheap and good: Mannol Fully Bi-Synthetic Engine Oil Longlife 3 5w30

The car runs well, no problems starting up, no significant oil burning.

I use Mannol 7715 on my 3.0tdi

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.

So I drained the gearbox while I was there and refilled with 1/4 Lucas oil, the rest 80/90

I installed an oil cooler on my buddy's 370z and he dumped in oil and a full bottle of this and I just scratched my head
