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.
Yeah, it’s not an engineer thing, it’s a sales tactic. The number one killer of any Toyota engine is extended maintenance times, and heat. Just like any other engine. The difference is Toyota will last you much longer, and fail exactly how it’s designed to if you do PROPER maintenance. In which very few people who don’t dabble in mechanics actually do.
Sales tactics and they also get credits (or maybe just charged less idk) from the EPA for lowering the lifetime waste per vehicle. Hence the super long life coolant and long intervals for ATF, and the 10k oil changes
