Hello all. Long time lurker, first time poster. I have learned an incredible amount from this site, and am hoping I can glean a little more information. I had a question, did quite a lengthy search, and can't seem to find anything that quite answers this question.
My wife and I both love older cars. Collectively we have a 93 jeep Wrangler, a 86 Suzuki samurai, 90 geo tracker, as well as a somewhat new 12 Subaru legacy. At the moment, I'm stationed at Fort Bliss, and before I leave here to go back to Ohio, we will most likely be picking up another samurai or tracker.
The question I have is:
The jeep specs 10w-30 or 5w-30 dependent on temp.
The Subaru specs 5w-30,5w-40 all temps. Or 10w-30,10w-40 at 0 degrees f and up.
The samurai and tracker both state that 10w-30 is preferred, but also state that 5w-30, 10w-40, 10w-50, 15w-40, 15w-50, and 20w-50 can also be used dependent on temp!
I am currently using these vehicles in El Paso, TX, but shortly will be moving this small fleet up to northern Ohio, and will most likely be there for the foreseeable future.
One last bit of information that might be pertinent is after I learned about the clearance deals at AutoZone (Thanks to this site for the heads up!!!) I purchased a fair bit of Shell RGT in 5w-30 and 0w-20( I also change oil on my moms car).
I don't mean to cause a flame war, poke a hornets nest, disturb the peace, cause unrest...
The question I have though, is can I consolidate all of these vehicles down to using one or two oils, so that I can simplify supply and also capitalize on any future rebates by buying a "universal" oil?
