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.
If that’s all she gets, I wonder how much longer she has… the 2gr is a great engine, but that trifecta seal is not cheap or quick to repair. And he’s not wrong in the regard that 10k oil changes kill engines; they do. In every regard. The longer you leave the used oil in the unit, the more debris it collects and carries through the ENTIRE system. Not only that, over time, engine oil does become acidic. So that only adds to the wear of the engine.
If you want your vehicle to last a lifetime, watch your engine speed, and change your damn oil(& more importantly filter) every 5k to get that old, debris riddled shit out of there. If you really want to go the extra mile to protect it, buy an extra quart of oil and flush the engine after you’ve drained the old, before popping the drain plug back in to fill. It’s all about reducing loose material that can potentially get between moving parts and cause more wear than the general friction between surfaces.
You’re gonna be upset with me when you read the trans fluid has never been changed and is still original and shifts smooth as new.
I took a 2010 Highlander to 250k miles with 10k oil changes and never changed the transmission fluid. It ran perfectly, shifted smooth as butter still. That being said it’s not going to hurt if you change it more often and do a normal change (not flush) of the transmission fluid after 80k miles. I don’t buy the “it’s all a conspiracy” stuff though. I will say there are far too many oil change shops that will lie about the oil they put in. I have caught several putting in conventional oil when I asked for full synthetic. Also if you are a low mileage driver then consider changing it more often at least every 6 months IMHO. For us we do 20k miles a year so that isn’t an issue for us.
Nice those v6 engines are beasts do you drive mostly city or highway do you drive soft? I also had camry over 300k orig transmission fluid so I believe in not touching it glad to hear your experience!
Half highway half stop and go. I don’t drive it soft but I don’t beat the shit out of it either.
I’m not mad, I expect that of Toyota. I rarely see any car, new or old come in for trans issues. But higher mileage cars pouring oil from this that and the other? All day long.
I do the oil in my Corolla every 5 along with moving my tires to the best possible position. I plan to flush my trans every 60k (only because it’s straight shift), and the other major maintenance schedule items as they come. Spark plugs, coolant at 100k etc. it’s all in how much you’re willing to put in to keep your vehicle in peak condition, and how long you want to keep the vehicle. I hope to get a good decade out of this new 22, while putting a grueling 35k a year on her.
I will admit when I get rid of my 2002 Avalon what ever newer vehicle I buy I will be doing 5k mile oil changes. I’m eyeing the Crown.
They’re pretty nice. I was disappointed to see them slap the A25 in it though, especially with a 0w-8 oil requirement. We don’t even stock 0w-8 for anything yet 😂 but would still be a good daily/family car in you maintain it.
Exactly me also. But use 0-20
