Hello everyone, first post here; I find this forum very helpful, it is great to confirm and see proof of different oil brands, properties and quality that some times are mislead by the market/average customer, and this is what I am trying to figure out..
Following forums questions:
1. What kind of vehicle you have = 160k miles 2001 BMW 3-series (E46) 325CI - 2.5L 6cyl in line 24v
2. What your owner's manual says = 5W-30 or 5W-40 API SH or higher, both may be used in any ambient temperature, changes accordingly to your BMW center (I do every 4000-5000miles and check oil level periodically).
3. Where you live = Michigan
4. How you drive = I always start the car and let it idle for 1-2min then accelerate slowly not passing 2000-2500rpm until it reaches operating temp; after that I really like to push the thing to 4000-5000rpm most of the times, and sometimes to the rev limiter.
5. What your daily drive is like = short trips 85% city during the week, highway trips during weekend (50-100miles).
6. Whether your car has any known problems = has a oil pan "sweat" that doesn't even drip, rest is all clean with new gaskets and car works perfectly.
I am using Mobil 1 5W-30 extended performance (Walmart) and genuine BMW (MANN) oil filter.
Now here is the questions;
-Previous owner was using 0W-40 Castrol Edge, should I go back to this oil viscosity?
-BMW used to have Mobil 1 as approved/recommended oil, now it is not in the list anymore (they recommend Pennzoil, Castrol, Genuine BMW) is it really changed or is it more like a "business" deal?
-What brand/model of oil DO you guys would use on this car w/ this mileage? I plan to track-day during summer.
This is kind unrelated:
-I noticed some deposits when changing my valve cover gasket (pics below), should I use these oil flush products in the following oil changes? or this can damage my engine/oil pump? if yes, which product do you recommend?
-Same question on these anti-friction additives (like liqui moly MOS2), should I use it?
-Same question on these Seafoam products that goes in the intake to clean the valves/pistons, should I use it? (my piston pics below)
Thanks!
