I checked out the Castrol Syntec specs and along with SG it also says SJ. So, I guess that means it is out, right???
Good Grief People!!!!!
This is getting silly!!!
Here's some FACTS...make your own judgements..
--Kawasaki brand oil is NOT SJ...its SL!!!!! You know, the ZX14 guys...180+ HP. Shame they aren'et as "smart" as BMW engineers. (who brought us the rear end we all know and love
--Suzuki brand oil is SJ! Shame they don't know they are ruining their engines!
--Yamalube m/c oil is SJ! Just imagine how their poor owners are being swindled...after all, SJ?????
--Contrary to posts on this list and common perception there are MANY cars today with higher HP/Liter than our LTs. My Wife's Cobra (4.6 L, currently in the neighborhood of 450 RWHP), BMW M3's, my Acura RSX-S, Suburu WRX, etc. Most have synth fills from the factory and ALL use SJ!!!!! GASP!!!! Why isn't it that we aren't all getting flats from the shrapnel being spread as these poor, under-oiled engines grenade themselves all over the country???
--About the famous BMW service bulletin... its over 8 years old, doesn't even mention the LT and since BMW doesn't/won't release them, how could ANY BMW owner even know about it let alone be held "accountable" for not complying with it?????
--I've also heard about a "letter" from BMWNA that states that they will not honor the warranty for any motor that didn't have "motorcycle" oil in it... Hmmmm... I never got it, I don't know anyone who got it... My owners manual doesn't say that and neither does the warranty book for my LT, GS or Wife's GT so just what "standing" does it have???
I'm sorry but while oil threads are often held up to the same ridicue as political and gun threads, IMHO they are even WORSE!
I've NEVER heard a first person account from a BMW owner (or any other brand for that matter) of an engine failure due to the use of an "inadequate" oil.
Here's what "I" do, feel free to imitate, modify or ignore as you see fit.
I put in oil...
--of the appropriate weight...
--of a major brand...
--changes every 5k miles (easy to remeber 5's and 0's
--if I go to 7 or 8 k because of a trip I don't/won't lose sleep about it.
I seem to remember a famous saying on this list . . . how did it go???
JUST RIDE IT!!!!!
