BMW parts reviews

I was thinking about throw in the 195 on the front end the front end buying a pair of Pirelli P-Zero PZ4 (215/45/20) on the rear wheels.

Got new tires on my I3s. Drive is smoother than stock tires.

On an old e36, 5w30 full synthetic no matter the brand would often cause some leaks. Switched to some thicker Rotella oil made for diesels and suddenly no more leaks.

Mobil1 15w-50 (red label) was always good to me, and readily available at wally world. Never had lifter tick in my S50US, on track or otherwise, and it went to 298k before the head gasket gave up. Absolutely could have resealed the engine and ran it another 100k+ (swapped an S54 instead).

Brand is personal preference tbh.. ive seen good and bad reviews with royal purple but no evidence that its actually bad. My main 2 that i use are Delo 15W-40 Full Synthetic Heavy Duty Turbo Diesel oil and when thats sold out i run Mobil 1 Full Synthetic 15w-40. And i put a K&N oil filter every time, changing oil at 5K miles and ive had no issues using it as a daily and autocross car. Backroads racing on the weekends, roadtrips, some drifting. Got 271K miles on it and no motor issues.

Liqui-Moly is also good, as are Amsoil and Pennzoil Ultra Platinum. I never had good luck with Mobil 1.

I have ngk coils in mine and they've been fine for 50k+ miles.

I recently replaced the flywheel and clutch in my '09 135i with an exedy kit which ended up just being repackaged Luk components. The old one was also a Luk and identical to the new one. I think most "aftermarket" kits just repackage the Luk flywheels or machine their own single mass ones. Only had it for a month, so can't judge longevity.

I personally had Bilstein OE replacements on my E46 that were leaking and failed even though they were practically brand new when we removed them.

My mechanic said that a small amount of metal flakes in the engine oil filter is normal, but the amount here is significant and shows theres a something going wrong.
