Engine oil MOTUL or OEM BMW

motul 5w40 8100 is great

Have since switched to motul 5w-40. The extra protection.

I run 5w40 motul because of upgraded turbo and other fuel parts. Its been very solid. ????

bmw oem 5w30. n ai cum sa dai gres.

prietenii mei... baga motul cu certificarea aferenta, ziceau ca e o idee mai silentios motorul.

However my "go to" oil in the last two oil changes was the Motul Specific 508 00 509 00 0W-20.

Last change , used Motul 8100 0W - 20 Full synthetic

Motul 8100 X Clean 5W30, used by reputable specialist Mini garages here in the UK and is in my 2018 JCW.

I have been running Motul 5w30 Xclean EFE and have used Pennzoil Ultra Platinum as well.

This sub loves to praise motul, but it caused me to foul up my spark plugs and have misfires. I tried both the 5W30 like the manual calls for and 5W40, but shortly after I changed to motul my plugs fouled up. I replaced them, they fouled up and misfired again. I tried it a third time cleaning the MAF sensor, checking if the plugs were torqued okay, checking the seal on the coil packs, etc... still fouled up. I finally guessed it was the motul and did an oil change away from motul and swapped the plugs again. 14k later no fouling.
