I just recently purchased a 2020 Camry LE(normal version, not a hybrid), but had a few questions:
I saw some stuff here and there mentioning having the dealership reset the adaptive transmission if the vehicle was used(which this one is) to ensure it starts out fresh and prevent jerkiness from it adapting to the previous owner. Is this true?
What kind of oil specifically does this car take? I’ve seen some claim it can take 0W-20, but I’ve seen some say you should only ever use 0W-16, as it’s better for the engine and other oils can cause problems. This video this guy mentions the same, about having to use 0W-16. https://youtu.be/HlC3ZfzefCs?t=107
Is he correct?
Are electrical and battery drain issues common with this model car? Are there any signs and ways you can tell if it’s happening, and is it hard or expensive to get fixed?
Usually you can go a little bit thicker with the oil up to a point until the variable valve timing will not function correctly as it expects a certain viscosity oil at running temperature. Youcould switch to 5W20 after 100k miles. Heavier oil lubricates a bit better. It has a thicker oil film so the contaminants have to be larger to be thicker than the oil film. It’s important to use the proper fine filtering oil filters when using such thin oil.
22 years ago you could put 20W40 in such an engine and it wouldn’t matter as long as it wasn’t started when it’s very cold. All engines are made to handle very thick oil as this is will happen to any oil in very cold weather. The engine is made to start at -30F even if the coldest it gets for you is -10F. So 0W at -30 is like 10W at -10F.
His advice is not just ridiculous, and it’s actually potentially dangerous. The OP’s engine has Variable Valve Timing, which requires the correct oil viscosity. Putting “heavy” oil in that engine would almost surely screw-up the VVT.
My engine (very possibly the same engine as the OP’s) is supposed to use 0W-16, but the manual states that if you’re just topping-off the oil, 0W-20 is acceptable, and that at the next oil change, you should use 0W-16.
