Has anyone run a test using 5W30 in place of water? (0W16)
Kinematic Viscosity 5W30 is 10.3 @ 100 degrees C.
Kinematic Viscosity 0W16 is 7.6 @ 100 degrees C.
So about 30% difference.
The new water oils is a conspiracy for two reasons:
Better fuel mileage required to meet the EPA standard.
Wears out your engine much faster, thus you buy a new car.
Has anyone performed an oil analysis to compare how running 5W30 turns out?
And no it will not destroy your engine. Doing 10K Mile oil changes will destroy your engine.
If there is no one brave enough to try this, my next car will be a brand new Camry (in a few years). I will take the risk for this community and run 5W30 as soon as I get home from the dealer. I will document all my oil changes and see how long the engine lasts. By the way I change my oil every 4000 Miles.
As for you keyboard warrior engineers and mechanics that seem to know everything. The smaller oil rings in modern car pistons will still pass 5W30 with ease. Oil pressure is at around 50 PSI it will go through anything.
I change the oil in my 2020 Camry every 5000 miles. BUT my gf has a 4Runner she bought new in 2016 and she has hers changed every 10000 miles and it has 205,000 miles in it now with no issues. So hell I don’t know. I just don’t know.
Is it leaking oil anywhere around the engine? Check right under the bank one head, in between that, the block, and the timing cover. If not there, check around the oil cooler.
