Engine oil MOTUL or OEM Subaru

During all my oil changes, I\u2019ve taken a sample and sent off to Blackstone for analysis.\n\nEven after 12k miles, there\u2019s still enough TBN left that I could have continued using it out to 15k miles.\n\nDissolved metals and other elements were still within universal engine norms so it wasn\u2019t like the sample was abnormally contaminated.

Pero nag stay ako sa motul since 2019.

General rule of thumb for mqb cars is if it\u2019s stock, run stock spec oil. If it\u2019s tuned run 5w40. Personally we run Motul 8100 xcess gen 2 5w40 in 3/4 cars.

I run Motul 10/30 in my motor, helps the piston slap on cold start from the forged pistons.

I'm using motul 5w40 8100 x clean and it's great on my m54b22. I'm loosing little to no oil between changes

Looks fine to me, oil is relatively cheap, forget all the mileage crap and change it sooner if you are uncomfortable with the way it looks. I change my oil every 2000 miles, or whenever I go on or do heavy riding. I also switched over to Motul 7100 simply because it’s red and I can see exactly when it starts to discolor. A motorcycle mechanic told me the number one reason for engine failure is dirty oil so I started changing it frequently.

My 276k mile Xterra still trucks along with motul, every 3k miles.

changing the engine oil and using motuls 10w40 fixed it and getting mileage around 40.

Yeah? I’ve been using Subaru oem oil in my 260kmile 2015 forester. It only burns a little.

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.
