For me, first one at 2K and I'm doing an OCI every 5000 thereafter so, I will be due in about 500 more miles @ 7K. Thanks for reminding me!!!

That PU "Penzoil Ultra" 5W-20 is a good oil. I went with TGMO “Toyota Genuine Motor Oil” 0W-20 for the first change and I have some
Eneos Sustina 0W-20 for the next one. Should have done it the other way around but couldn't find the Sustina at a good price (it is expensive) when I did the first OC.
Mazda GF-5 0W-20 (made by Idemitsu) is suppose to be good oil at a decent price with higher VI (viscosity index) numbers than the dealership Subaru oil (also Idemitsu oil) so I might try that one next time if I can score a case at a good price at one of the dealers.

johatan25 In case you are considering what oil to use...check out "Bob is the Oil Guy" website:
http://www.bobistheoilguy.com/forums...s.php?ubb=cfrm -- CATERHAM is the xpert on 0W-20 oils and a year ago he did comparisons of all the brands and listed them in order of his preference. Eneos Sustina and TGMO were top rated at the time but, they say the newer API SN Toyota oil is not the same as the older SM oil that was tested in the past. New stuff has a "trinuclear moly" formula that replaces the actual molybdenum content our factory oil was loaded with. Speculation is the Toyota oil is made by Exxon now meeting the Toyota specifications. I tried to find the original post. If I come across it I will update. Anyway, BITOG website is a good oil reference site for sure!!! Oil is oil as far as molecular structure but there are different grades of base oils and it is the "additive" packages that differ among manufactures that distinguish performance characteristics. Just about everything you need to know about oil and more is on BITOG!
