[quote=paramount]I had read in my manual that Mobil 1 was the only approved oil for my 328 (except BMW’s oil), but my filler cap has Castrol stamped on it.
At any rate, I went with Castrol Syntec 5w40.
And I completely agree it’s not just BMW that costs $100 for an oil change.
And I also agree that most BMW’s are leased or pre-owned.
My 328 was about the same cost as a new Corolla with 36k miles; but it ain’t no Corolla that’s for sure.
I was at a mini dealer (escondido) test driving a clubman s with a friend, and the salesman was telling me I could install a turbo, chip and put a performance exhaust and beat a 335.
I am definitely considering a chip, for some reason my 328 has a slight throttle hesitation that drives me crazy.
And by the way, there are a lot of 328’s on the road and for good reason, don’t try this in a Camry or Accord (155MPH in a 328 in California):
By the time you add a chip, turbo, exhaust, and probably needed upgraded suspension and brakes + labor..All that money + selling your 328 would put you in a 335 with money left over to do budget tuning that would not make the tuned 328 close. Trust me on that one…Several friends did just that..Sell the 328/330 and got a 335.. Actually a lot of them got the 135 and tuned the crap out of that. The n54 in the 135/335 is easily tuned. The n20 in the newer 328 is easily tunable…
Chipping a non-turboed engine really won’t boost performance significantly and won’t be worth the money. You’re looking at 8-10hp gain at most.
