Good Morning.
First off, thank you in advance for taking the time to read my post. There is a great amount of info here on BITOG and this site has become a favorite of mine. Thank you.
Also, sorry in advance for the long read.....
1. What kind of vehicles you have
2007 Subaru WRX STI. Mods - catback and SPT intake w/mild tune. My daily driver.
2000 Toyota Celica GT. Mods - catback and AEM intake. Wife's daily driver.
2006 BMW 530i. Family weekender and occasional commuter.
2. What your owner's manual says
STI - ILSAC GF-4 or API SM energy conserving
Celica - ILSAC or API SJ energy conserving
BMW - BMW High Performance Syn Oil API SH or higher
3. Where you live
Royal Palm Beach FL - winters 40F +, summers 80-90F, 100% humidity.
4. How you drive (easy? hard? fast? slow?)
STI - Moderate for general commuting. No race or track. Granny shifting @ 3500 - 4500rpms. Top speeds to 120ish sometimes.
Celica - Moderate for general commuting.
BMW - Moderate for weekend use or commuting.
5. What's your daily drive like (short trips? long trips? city? highway?)
STI - 135mile daily commute, 15 local, rest highway. Average speed 75+mph.
Celica - 75mile daily commute, 15 local, rest highway. Average speed 70+mph.
BMW - Varies by use, but averagre 30miles per week if not used for commuting.
6. Whether your car has any known problems
STI - was modded but returned to stock condition before I bought it in 06/09. 3rd owner.
Celica - None, original owner.
BMW - bought in 04/09. Routine dealer servicing. 2nd owner.
7. Current mileage/oil used/ miles since last OC
STI - 47164/ Castrol 5w30 syntec/ 3519
Celica - 159056/ M1 5w30/ 1414
BMW - 55476/ BMW HP syn 5w30/ app 7000
On the STI and Celica, I change the oil every 3-3.5k miles, and have yet to change the BMW oil, but I want it changed every 7.5k instead of the BMW suggested 15k.
Oils I've used on the STI - M1 5w30 x1, GC 0w30 x2 and now Castrol 5w30(last 4) w/OEM filter. Celica - M1 5w30 w/M1 filter for last 3yrs.
I would like to change the oil in all 3 cars, and based on what I've been reading here and elsewhere, I would like to go this route..
Celica - M1 EP 5w30 w/M1 filter @ 5k OCI
BMW - GC 0w30 or M1 0w40 w/OEM filter @ 7.5k OCI (I have 7qts of BMW HP 5w30 sitting in the garage, so I may just use that for now and then switch).
STI - That's the big ??. There are many opinions about oil use and the STI, but I'm thinking about going with Rotella T6 or T5. A local subaru tuner told me about M1 semisyn blend 10w30, which he has been using with great results for awhile and has been suggesting it to all his customers, but I cant find that. And I would still like to keep the 3.5k OCI.
I'll send out for a UOA for all 3cars @ next OC.
Looking forward to reading your comments.
Thanks again for your time, and sorry for the long read.
