Bill I do agree with you on your point that any SM oil is good for 6-9k miles in most cars under ideal cicumstances. In any case, most SM oils these days are close to being true synthetics by the grp III definition.
I don't think there is any group 3 base oil in any of the popular conventional oils, just group 2 (and in some cases perhaps group 2+ but I don't think there are too many of those)
Hmmm... I was under the impression that to make the increasingly popular 5W-20 it either had to be a high percentage GIII Blend or at least 100% GII+. As a matter of fact I understand it the cheapest way to formulate it may be with primarily low-level GIII (60-70%).
Looks good,
but you could do better with synthetic oil.

Perhaps with 5w20, but I was referring to 5w30 here (since this UOA is with 5w30)
I know you have passed the 60k warranty period and know how much you like to save money. It might be interesting to see how a UOA would look with PP at 10k vs 5K on a dino AND you save on a filter as well, if you are going to spend a whopping 99 cents for a quart of oil you might as well get your money's worth

In then next few weeks or so ill be tring auto rx and gtx eventhough the valves are sqweeky clean ill be courious if i notice any change in fuel economy. Since running Series 3000 my truck doesnt seem to like the thick oil.
Always love reading Bill's reports! I'm a tiny bit bummed we won't be able to compare UOA's anymore
I guess we'll have to see how the 2.2 Ecotec compares....going to have a UOA of some Valvoline in about 2k miles.....only gonna have 3K on the oil but interested to see how it does during break in and how it compares to the 1.8L
It't wil be hard to match the Toyota UOA's I bet

25k @ the time of the UOA
Normal Fram air filter. Paper.
Of all the UOAs I've had done on MANY engines I've always had single digits.(I've had 1 and zero before) Here they salt the roads like crazy and with the low humidity here its always dusty.
Just good filters and making sure that everything is put together correct.
Take care, bill
Utah and freezing temps? Its hard to get my mind around it.. I am not sure if someone reading this from Ontario can extrapolate oil's performance in Canadian winters..
Yeah, ok it never gets below freezing here.
Bill are you sure that your Fram air filter is paper? The one I have is a synthetic media. Like a batted polyester, something like a felt. It has few, large pleats. Similar to the OE filter. Except the Fram has a plastic frame with rubber gasket. Actually says made in isreal, and identical to "Purolator" filter.
The reason I ask is because I would prefer a paper filter for my Corolla but cannot find them. All have similar media to OE filter.
They pretty much are all the same although they can vary from Fram to Fram...especially with the plastic setup. I used to use Purolater in my Matrix (same engine) with never an issue. Just about everyone else other than OEM seems to get their filters from the same Israel plant
