Engine oil Castrol or Lucas
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.
I use Castrol R, smells great and reminds me of riding 2 stroke bikes from my younger days.
Castrol full sinthetic.
Or Motul 7100, even better.
I use Castrol on my z4. Works like a charm
Castro Synth. is all i ever used in my BMW 60,000miles runs perfect change every 7,000 miles
(5w-40)
After some research I heard people use 5w40 to quiet the motor down and lubricate the lifters better for high mileage engines. picked up some castrol edge 5w-40 and it runs buttery smooth, noticeably quieter and another big thing is oil consumption drops A LOT due to the oil being thicker and harder to burn or leak. I used to need maybe a quart a month now Ik down to half a quart a month.
I use this Castrol Edge 5w40 for 5 years already in my e46’s m54b30. No issues. Trying to stick to 10k km intervals.
In my e39 M54B30 473k km I am dumping Castrol Magnatec 5w-40.
Nothing to complain.
I use Castrol EDGE Fully synthetic oil in my 2013 Mazda 3 skyactiv. It does burn a little but I did not have any issues.
