Supertech does not specify, but Warren's own MAG1 brand calls their high mileage product, which I assume is the same a synthetic blend, although what's the reall difference between a conventional and a syn blend, couldn't you theoretically have a better conventional than a synblend, you couldn't call a conventional made of all group II with a high viscosity index bordering on being a group III a synblend, but you could take a group II that's on the poorer end and add a little group III to call it a synblend and it'd technically be a worse oil than one that's only allowed to be labeled conventional, right? Although I think mostly now the oil companies are using rather high quality group II base stock and combining them with enough group III in order to meet the newer more stringent requirements of API SP and ILSAC GF6a, at least for 5w30 and 5w20 grades.is this conventional or a blend?

As a preventative measure or trying to fix oil consumption? Asking because (from my understanding) the 1ZZ got updated rings and pistons from 2003 to 2008 model years, which eliminates the pre-2003 1ZZ oil consumption issues.Kreen definitely helped the oil burning in my previous 1ZZ-FE in a 2001 Corolla. A bit difficult to get but works great. I actually have some in my 2008 1ZZ-FE currently.
Yeah I’ve seen some videos on the rebuilds of these engines. Rings all stuck and the return holes clogged.I rebuilt 90+ of these engines, it requires a tear down, which can actually be down with the car inside the car or pulling the motor, I prefer pulling the motor, that way I can change the main bearings as well. long story short, the piston oil return holes need to be re-drilled bigger and by doubling the oil return holes. Different oils aren't going to help with the oil burning per say, maybe some engine cleaners that people use, best is pulling the pistons, and installing new rings, along with a cylinder head job which can be down at home with some fairly inexpensive tools.
you will have zero oil consumption afterwards, and I have seen some scratched up engines, none ever burned oil between even extended oil change intervals, just never ever hone the cylinder walls as Toyota recommends against it, and it will lead to oil burning.
This video has been shared here many times before, but I feel like it belongs in this thread.
