My Toyota owners manual says to go 10k between oil changes if using full synthetic oil. It dosent mention changing the filter out sooner. When I do use synthetic oil in it I just leave the filter on the whole time and usually it's just a typical filter. Never been a problem. Apparently Toyota isn't too worried about the filter I guess. I do believe that Toyota cares very much about the longevity of their products. It's probably the top reason theyer one of the largest manufactuer of cars.
Mazda says 7500 as does my ford. Motor craft cartridge in the Ford looks as good as new after
I've had 4 (actually 5) Toyota's since 1980 and put 150,000 miles or more on all but one (destroyed in a fire). I had a significant commute at one time. In the non-synthetic oil days, I changed oil & filter every 3k miles like clockwork. Toyota's are darn good cars in my book. In 2007, I bought my wife a Mazda6 and still have it. It's got 130k and I've always used synthetic oil (mostly Walmart SuperTech) and factory OEM or PureOne (purolator's higher-end) filter cartridges with a consistent 5,000-6,000 mile OCI. The car runs like a top. I bought another Mazda6 in 2009 but it was stolen a few years later. Great car while I had it. After that, another Toyota ( '12 Tacoma) w/a 4-banger. Factory bulletin said to do 5,000 OCI's on it. Bought it new and put 65k miles on it but, gave it to my oldest son. Now I have the '18 Mazda3 and am liking it a lot.
The Mazda3 owner's manual says 5000 or 7500 OCI's. Just bought it 2 months ago and now has 2k miles on it. I'm doing to dump the factory oil at 3k because I can see the reflective particles suspended in the oil and it's bugging the daylights out of me, even though I know those particles are sub-micron and won't hurt anything. I want fresh oil going into winter.
...Sorry about the oil/history rant...
