Engine oil PETRONAS or Lucas

I used lucas in my honda and will use it on my next change for harley

Personally I run Lucas oil in mine, not just my current zzr600, but even my older vintage bikes when I had them. It isn’t crazy expensive and is high quality.

I run Lucas in all 3 holes and my bike has been cooler, less noise and shifts smoother than it did when I got it and it had Harley fluids in it.

Right now I have some Lucas High Performance, but the brand is relatively immaterial to me. As long as it's a reputable brand and it meets the spec in the manual.

Petronas Syntium 5w 30 on a mercedes and audi a6. No complaints at all, and good price

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.

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
