Engine oil OEM Toyota or OEM Mazda
Really looking forward to getting that first break in oil change done and go full send. I do have a giant problem with this car though... I F'N LOVE IT!
For Naturally-Aspirated Skyactiv engines, it is highly recommended that you use Mazda's own(Idemitsu) high molly GF-5 0w-20. Arguably it is one of the best oil for skyactiv engines.
I change mine every 5k irregardless of whatever Toyota says. Oil changes are cheap insurance to your engine if you intend to keep it for the long term.
Toyota OEM oil has 10x the amount of thr dry lubrication additive molybdenum in its additive package. The dealerships use bulk Mobil 1 oil when they do your oil change. This is why everyone should change their own oil.
Mijn prius uit 2005 krijgt niks anders. Ik rijd er al mee van 220k tot nu 397k. Still going strong!
But then we replaced it with a SkyActiv Mazda3 that used 0w20 and proceeded to have a good long history with that motor that had 0 oil consumption in 125K miles; I did all of the oil changes myself and it was always 4.5qts in/4.5qts out every 5k miles.
Use toyota 0/16. Or Mobil 1 0/16. Liqui moly is also very good.
Fun fact, on a gen 4 Toyota Camry (1997-2001) with the 5S-FE 2.2-liter four cylinder, the low oil light doesn’t even come on until you’re like 2.5 quarts low!
I check the oil a couple times a month, mostly because it's leaking oil a bit and needs a top-off every thousand miles or so.
Brought it in for 5k ToyotaCare at the dealership I bought it from. Used wrong engine oil (at least they listed wrong on the service sheet but promised they did use 0w20) - GRC is only model where 5k or 6 month oil changes are standard. 2500 miles if driven hard. Fucked up the trans oil I asked them to change - used wrong oil type. Fucked up tcase and rear diff oils. Found oil spilled on some pieces of the subframe. Of the 2 test drives they did doing the warranty covered alignment they had 10+ drive pulse hard acceleration /braking/cornering alerts on both 4 mile drives. I changed the engine oil, trans, tacsee, rear diff, cleaned oil they spilt after picking it back up. They said they'd corrected their errors only after I got Toyota corporate involved. I didn't trust them to do anything so corrected all myself.
