Engine oil Mobil or LIQUI MOLY
Liquimoly is by far a better 5w40 to put in a bmw.
Mobil 1 Definitely. 0W20 in my 2023 Sonata Limited. 5W30 in my 2014 Sonata Limited.
I do my own oil changes. dexos is pretty much a quality certification standard and I use Mobil 1 Fully synthetic 0w-20. I did my first change at 1,5k then at 5k and will do one at 10k. I always replace the filter and I have a magnetic drain plug to collect shavings that may pass through the filter in case it ever is compromised.
Ive always used Mobil1 oil and filter and have 130k miles on my Veloster
I used OEM, Motul, and LiquiMoly oil. The only one that seemed to do anything with oil consumption was the LiquiMoly. I changed the oil every 5k miles and I had similar experiences as you until I did the LiquiMoly. Completely anecdotal, but I’m a believer. Been using it ever since.
Avoid Castrol. Use Mobil1 or LiquiMolly.
I'm using 5w40 and never had issues overheating in summer but im not doing half hour pulls. No oil consuption also. With 5w30 when driving hard it was eating a lot of oil.
Random guy who works on these cars here, change it at 5-6k regularly. Ignore the casuals here who don’t work on these cars, and especially Ignore the factory recommended interval. Your engine will last much longer, you’ll reduce wear on the timing chain, turbo, as well as other components. You’ll also reduce the chance of your piston rings getting glued together with carbon creating excessive oil consumption. Just change it. I recommend liquimoly oil.
5k or less with Liquimoly. Just had oil pan and upper timing cover replaced at 123k miles (plastic parts leak/ fail bc of heat cycles) and my timing chain looked like new, and not one spec of metal or debris on the bottom end. Unitronic stage 1+ since 75k miles.
My local shop in Canada does it for $125 plus tax and uses liqui moly oil.
I'm currently happy with Mobil 1, 15w50, except when it comes time to pay for it, yikes that stuff is pricey. First time I ran the Mobil 1, guess what happened?? Oil light flicker at hot idle. Replaced the low pressure switch, no more flicker. That switch didn't change characteristics just because I changed oil, the fresh oil was thinner, oil pressure decreased.
