3-Series (E46, E90)Chat relating to the BMW 3-Series from 1999 to Current. Models include: BMW 316i, BMW 318i, BMW 318Ci, BMW 320i, BMW 323i, BMW 325i, BMW 330i, BMW 328 Ci, BMW 328i, BMW 325i/xi, BMW 330Ci, BMW 320d, BMW 330d, BMW 335d.
I have a 02-325XI with almost 120k on it. I'm working on its fuel efficiency. I'm wondering if anyone of you have used eangine treatment chemicals that are supposed to improve your vehicle performance? Partiucularly a brand that is called Slick 50Plus.
I'm wondring if they do what they say they do also if they are compatible with BMW engine parts? If you got into any troubles after using them and so on.
Any comments ... or may suggest another brand/ type ...
Auto-Rx your engine. Use a non Group IV or Group V base stock oil, Group III is fine, and you wil be amazed at the difference. If you have more than 100,00 miles use the two botle plan. I'm 2,500kms into a 5,000kms clean phase on my E46 2001 325CI, difference already is amazing.
