Guys what you guys think about using toyota 0w16 in our cars? Since the 0w16 is made for direct injection etc

It seems 0w16 is interchangeable with 0w20 to an extend. Correct me if I am wrong but RWD uses 5w20. You might be able to get away with using 0w16 but there is a small risk, it can ruin your engine.

well not really so in US if you look at your manual it says 0w20 for best fuel mileage and 5w20 is ok too for warner climates so you see W or cold weight oniy affects things for cold start etc the normal operating temp weight is 20. So it is essentially the same oil.

0w16 us different coz its thinner, i heard differing things like theres a backward compatible version there’s supposed to be a rating to differentiate but I cannot see it on the Toyota bottles.

no its not an idea that makes sense,

Japanese engineers get paid houndreds of thousands of dollars a year to tell you what oil to use in our motors, follow what they say

0w16 is a new generation of oil designed for better fuel economy. Some of Toyota manuals stay that 0w16 can be replaced with 0w20, but 0w16 should be used during next oil change. Use it on your own risk. I believe, it would ruin an engine with over 100k or even lower. It is just my opinion.

0w16 was not out at the time

The shear value of a 16 will be very risky if you push the engine even slightly hard or let it get too much acid in it. The 20 is already too light if you push it hard as can be seen in the GSF/RCF/ISF all using 5w-30 with oil coolers on top of the heavier weight in an engine that has the same or even tighter internal clearances.

The 460 doesn't even have a cooler and you are going to put 16 in it? 16 only exists to meet fuel economy targets across a huge fleet with the only change to engines being a new, usually variable rate (really expensive and tend to break) oil pump needed vs designing entirely new engines or changing tooling/all oil clearances. It's never going to protect as well as 5w-20 or heavier and physically can't.

maybe that’s why 5w-30 was used in the engine before I got the car, what year is your vehicle how long have you had it what oil do you use? And how’s your mpg. I won’t be asking if I’m getting anywhere even 1/2 of what my city mpg should be

I have 5 5qt jugs of 0w16 I got on sale at Walmart for $3.50 each. Wondering when to use them. I think they will be fine in the LS460 for short winter trips, with gentle driving and a low mile oil change interval. I’m fine with the viscosity but worry about the Noack volatility.

A 0w16 shouldn’t be pushed at high RPMs, I agree. Film strength is a concern as well for the timing chain components.

but Acid in the engine oil is a result of how long the engine has been run as the combustion byproducts break down the oil and turn the TBNs into TANs. the viscosity of the oil wouldn’t be a factor unless you assume a lot more blowby occurring with this thinner oil than with 0w20.

It should blowby more since the cylinder walls and oil rings will have thinner oil coating them that runs off faster and wont build up as strong of a seal plus a naturally thinner oil will suffer TAN breakdown faster simply due to the fact it has less room to wander before becoming dangerous.

The timing chain.......well I'll be honest I didn't even think of that. I have a 430 and all my other V8s are pushrod with extremely short timing chains that have guides the full length. I have no idea if the 2UR will kill itself like a GM 3.6 does if the film gets weak from breakdown. Best to assume it will and not risk it since internal guides and chain are NEVER easy unless, again, it's a pushrod engine.

Well for that price I would have bought everything they had too lol! Not sure what I would have put it in since all my cars except one get some type of 5/10/0w-30 but damn that price is right. Probably buy a bear corolla or something, I don't know......

I have an LS430 with 220k on it that I beat the hell out of and I get 18 when being aggressive (every stop sign, red light, full power and many 100+ runs. Today I hit 100+ 5 times) and 26 average if I drive normally (3500 rpm accelerations) and right around 30 highway.

I may have actually found a 460 spec that I like and will be able to actually add my data point to your question if I end up replacing the 430

life is about choices:
I go with what engineers design for the car and what is spec'd for the car

i would not run 0W16 in this car, especially not an old one.
