Scotty I have a 2020 Camry And the cap says 0-20 oil. I live in Texas and it’s hot. A mechanic of mine says my car would last longer with 5-20 (thicker oil). What u think?
That sort of thing may have applied 50 years ago but for a modern car follow the manufacturer's recommendation.
I think he's full of it.
Especially on a 2 year old car. What a terrible idea.
Unless your mechanic friend is one of the Toyota engineers who designed the engine for your Camry, you should use the manufacturer’s recommended 0w-20.
No way.
No. That's a thing of the increasingly distant past.
When I changed the oil in my 1979 Pontiac for the first time, I was slightly puzzled that it didn't have a specific weight requirement in the owner's manual -there's a chart of temperatures and oil weights. Old cars didn't have the engineering that new cars have, which my younger self is accustomed to. That car can use anything from 5W-30 all the way up to 20W-50 depending on driving conditions and ambient temperature. I use 10W-40 from October to April or May, then I add a quart of 20W-50 in place of a quart of 10W-40 to slightly thicken the oil in the warmer months. There is no overdrive, so highway cruise is a much higher load on the engine than your 2 year old Camry.
My 1999 Ranger's engine was engineered in the mid 80s, and even it doesn't require anything but 5W-30. More viscous oil helps lubricate and cool engine parts on very old engines more effectively. Modern engines don't need it at all, unless the owner's manual says. Don't destroy your new car's engine listening to that guy.
Well I would say check your manual. Oil viscosity is selected for engine and region you live in. So it may be true if your manual says you can or should. Some engines NEED to use 0w20 all the time. Others have different advised viscosities based on ambient temperature. Check your manual.
