    Mixing Pennzoil Euro viscosities

    So I found the following in another BMW N54 thread where they mixed theses two pennzoil euro oils and the used oil analysis showed great results after 10k miles. The proof is in the pudding my friends! https://www.e90post.com/forums/showthread.php?t=946279

    So it seems consensus is that mixing viscosity and ratings from same oil manufacturer and type (in this case Pennzoil Euro) will not damage engine components and will still be able to safely achieve the OEM recommended OCIs.

    The last model year car BMW outfitted with the N54 engine was the 2016 Z4 35i. BMW still recommends LL-04 for all cars in EU due to <10ppm sulfur in gas. Only top tier gas (shell, chev/tex, BP, etc) here in US is guaranteed <10ppm, otherwise up to 80ppm is allowed to meet the EPA low sulfur...

    Same base stock same Manufacturer means additives are compatible but with different levels of dissolved or suspended solids.

    I’m only running Pennzoil Euro oils 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

    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.

    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...

    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

    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

    Love my 2018 M550ix!!!! It’s has abt 4k mi on Pennzoil Euro L (LL-04) and planning on going to 5k mi before changing oil

    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...

    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?

    And LL-04 appears to be easier on Catalytic Converters or DPFs for Diesels

    Mixing Pennzoil Euro viscosities

    Because I purchased a crap ton of Euro L (LL-04) from Walmart for like $20/5qt. Lol

    Mixing Pennzoil Euro viscosities

    Full SAPS LL-01 has richer additives and therefore tends to be less picky on gas quality (mid tier vs top tier)
