hey Scotty, I have a Toyota Camry SE from 2012 that my dad bought for me used with just over 100k miles on it and I love it. 

The thing though is that it burns oil at a slow rate. If my oil is at the high recommended mark on the dipstick and check back in 2-3 months, it is usually of the end of the dipstick and there have been a few cases where it didn't even reach the stick. I drive the car about 15k miles a year and have had it since Nov. 2020 and I also have a high output alternator for a power inverter in my car and idle a lot and drive my car in one gear lower than most efficient to help it keep the batteries charged. The car is always at about 50% weight capacity and I do accelerate moderately quickly to keep up with traffic and avoid wrecks in my hell hole of a city. I also only drive on E0 gas as I find the efficiency overpowers the extra cost in my experience on the highway which is most of the miles I get on my vehicle.

The question I have is how often should I change my oil? I feel like the higher rpm's and higher strain on the engine with a high run time on the vehicle, I should probably change my oil every 2 months or every 2-3K miles on it because that's when the oil sharts to get noticeably different in color. But my dad follows a strict 3-4 month 3-5K miles before oil changes and never gets to it quickly when he gets to that point anyways. (my dad "own's" the vehicle and we do our own oil changes)

I would imagine more than necessary would be a good idea in this case and since he watches your videos too maybe he'll change.

God Bless
