I have used LL-01 on my 2001 BMW 540 M-Sport since new. 23 years later and 367,600 miles I still have the original catalytic convertors and all factory emissions equipment working perfectly fine on the car. It is daily driven.
Inspiring! Although very different engine with different power curves. Forced induction engines are much harder on engine oil that can negatively affect the cats. What were your OCIs?
Pnly way it will affect catalytic converters is if your engine is burning oil.
Were? I still daily drive the car...since new. 7500 mile oil changes, only LL-01 or in the past year, occasional LL-04...whatever is on sale at WalMart.
I have gone back and forth on LL-01 and LL-04 on my M550ix as well. It's on a stage 1 making 570hp at the crank after the last dyno test on a MainLine hub dyno.
Over time, blow-by can reduce engine efficiency as it coats parts of the intake in oil and fuel. In forced-induction and intercooled engines, blow-by often coats the inside of the intercooler, severely affecting its ability to transfer heat and cool the intake charge. These issues become even more apparent with age. As piston rings and cylinder walls wear, more and more fuel and oil is able to pass into the crankcase and eventually into the intake system.
Love my 2018 M550ix!!!! It’s has abt 4k mi on Penn Euro L (LL-04) and planning on going to 5k mi before changing oil
Running an oil separator with fully functioning PCV system will greatly help in Forced Induction engines. Also a good idea to periodically check/clean the intercoolers
Agree and forced induction engines have higher likelihood of oil accumulation in the intake system all of which is preventable with proper maintenance and inspection
That all depends on how PCV is executed. BMW (except N54) usually has a very well-executed PCV system.
Haha.!!. so back to the topic at hand… best to run low SAPS (LL-04) if you suspect your engine is consuming oil or intercoolers are oil saturated? Both my N54 and N63 are running 100% LL-04 but want to add 20% LL-01 of the same Pennzoil base stock to help with bearing wear with increased ZDDP. I think it’s around 800ppm Zinc for LL-04 and 1000ppm for LL-01 from my research. So maybe insignificant from that perspective but Euro 5w-40 carries the API SP rating vs SN rating on the Euro L 5w-30
Highly doubtful. Please explain why…. Same base stock and similar HTHS both meeting the BMW LL standards. Please don’t post unless you have substance.
How much ZDDP you will have depends on particular oil.
I’m only running Penn Euros as the topic suggests. Mainly Euro L (low SAPS) and using top tier (shell) gas on both cars. With all due respect… I don’t see why LL-01/04 even matters if US gas is ULSG as everyone else suggests. LL-04 just has slightly less ZDDP
Additive packages are different. You have no idea if they work together well or not.
Low-SAPS oils leave fewer deposits on intake valves.
Same base stock same Manufacturer means additives are compatible but with different levels of dissolved or suspended solids.
An API SP license is nothing like a BMW Longlife-01 approval. That would be a technically inappropriate substitution.
