I have a 2015 Tacoma 4-cylinder stick shift 52,000 mi. I bought it new. The only maintenance I had to do was oil changes and I go underneath with a grease gun and grease all the fittings along the axle.
My mom's impreza will loose oil between oil changes with 0w-20 and will be fine with 5w-30. It burns the thinner oil.
My wife\u2019s 2012 Impreza is at 195k miles and I switched it to 0w-30 and then 5w-30 due to oil consumption. Was burning a quart every 1K miles on 0w-20, burns half that on 5w-30. I\u2019m actually considering going thicker.
The dealership here itself was using 5w-30 as the default for oil changes even though 0w-20 is stamped on the filler cap. After checking myself that Subaru said that would be OK, I started using it too for my own changes just to avoid flipping back and forth -- though I have no idea if that would be a problem. In any case, the Forester seems happy, even if the mileage may have dipped slightly.
Engine does become a bit quieter with 5w-30.
Just got the oil lab report back from the sample taken during the oil change I did at 15K miles. The previous oil change at 10K was performed by the dealership. So that means that whatever the Toyota dealership put in there at 10K, was not OEM Toyota oil.
I bought a 2008 toyota yaris for $5.5k on fb marketplace. Had a prepurchase inspection.\n\nI love that car for the exact reasons you mentioned. It\u2019s been with me everywhere ive gone, is super cheap on gas, and just requires oil changes every 8000 km.
Just hard to read with fresh oil. 0-16 was impossible to read on the dipstick when new in my 2022 Camry. Even my 2011 Corolla is hard to read.
Do not listen to them. I have a 2015 forester non turbo I used 5w30 and had all kinds of problems id get codes for over advanced timing on one bank and under advanced on the other, I was getting power loss going uphill, weird chattering noise.
The only thing I noticed that my 03 Camry burns more oil when I was obsessed with 95, im usin 91 now though its still burning oil but not as much as 95.
