It's that time again: someone whipped a U-turn into my 2002 Protege5, totalling it. I bought a super-clean 2010 Mazda3, and I'm wondering what 0-20 oil you guys recommend now.
Threw TGMO 0W-20 in the Odyssey after 50k+ Miles since new using M1 0W-20. Noticed a heck of a difference at start up... Much, much quieter. But since you're in So Cal, cold mornings won't be an issue
I like M1 but there's a huge Pennzoil following here as well... Both have good cleaning properties for this new-to-you Mazda
Take a look thru the UOAs for some real world data
TGMO is the best 0w20, no contest. Especially if you get a good price from your dealer. If you can't get it, M1 0w20 is hard to beat for the jug price at Walmart.
TGMO, Mazda, PP, M1, all great 0w20 choices, you probably can not go wrong with any of those. I prefer PP and TGMO, both have run quiet and smooth in my Accord, cant say the same for M1.
The new Mazda 0W-20 is supposed to be pretty good stuff as well.
2010 was the last year 5W-20 dino was ok. I personally ran on the severe schedule with a steady diet of Valvoline or Chevron Supreme 5W20. However my short trip (6k annually) heavily justified dino 5W20 due to Mazda's rigid service schedule not giving any allowance for syn usage.
