Engine oil PENNZOIL or OEM Mazda
2014 3, 0W-20 full synthetic (whatever major brand is cheapest) from brand new, every 7500 miles.
170k, runs like a top, burns not a single drop between changes, compression and fuel mileage exactly the same as new.
As long as you get name brand oil at the weight your owner manual says you'll be good, I run penzoil in mine and she seems pretty happy with it
Finally ended up with Penzoil Plat. Can't tell a difference at all when the oil is fresh. Also engine never burned oil on Penz.
I have been running Pennzoil platinum euro in my 16 GTI its entire life and its now at 125,000km. I ran the same oil in my 2007 GTI before I sold it up until 190,000km. Never had a single problem, neither cars burned any oil.
Pennzoil Platinum Euro 5W-40. It’s LL01 approved
I used pennzoil platinum euro blend in my 2014 Veloster turbo for probably 50k+ Atleast with no trouble.
I switched to the Pennzoil Ultra Platinum, which is made from natural gas and it's probably the best full synthetic oil available now, IMHO
I use Mazdas 5w-30 Ultra DPF. Mazda once said that this was the oil that they're using, so I guess what's used by mazda can't be too bad for the rex
I run 5w30 in my 17 tundra, 16 Corolla and soon my 23 4Runner. My Tundra was noticeably quieter after the switch. The Corolla was quieter, but the change was not as dramatic as the 5.7 V8 in the tundra.
On the Gen 2 Prius that have been several reports of Pennzoil Platinum full synthetic consuming oil much quicker, me included.
