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.
Fellow mu-X owner here! If you're thinking about upgrading from the standard Isuzu Genuine Motor Oil 10W-30, check out the ZIC X7 Diesel 10W-30 Fully synthetic. I used Amsoil Turbo Truck 5w40 too (10k km interval) but it's expensive for my Garage queen mux haha. Mobil Delvac1 5W-40 is good as well.
I have Signature in my 25. Smoothed out the engine noises quite a bit.
Engine noise is a little, well noisy, mine is less rumbly/vibrationy after I changed my oil and used Amsoil Hybrid oil. I can’t generally feel anything when the engine kicks on now, before I could definitely feel it every time it kicked on.
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 switched oil to AMSOIL signature series synthetic, from everything I read, it out performs other oils, used to use Mobil 1
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.
My 2016 GT350R has almost 25K miles and has never needed oil between changes. I use Amsoil every 5000 miles, sooner depending on track abuse.
My biggest regret, not swapping out the shitty 0w-20 factory filled oil for some 5w-30 Amsoil, Motul, or Pennzoil Ultra platinum the moment I took it home. Don\u2019t wait till 1k miles.
Get a catch can but that mobile 1 oil you are using is for shit . Amsoil is best for mustangs and the best for that matter period it\u2019s cost but you can run it 25k
