Anyone using other than 0W-20 oil?

This might have been brought up in other threads. If so, send me a link.

Is any one using other than

$54 0W-20 oil Toyota/ exxon mobil Case of 6 Quarts Full Synthetic TGMO SN 0W-20 Oil

0W-20 oil in their third gen.?
I spoke with the deal and Mobile about other choices and both said 0W-20 for fuel economy and closed tolerances in the engine. I don't know it they are just towing the party line or using a 5w-20 or something else will make a huge diff.

 

Are you having trouble finding 0W-20 and that’s why you’re thinking about another viscosity?

 

Nope. 0W-20 only

Manual says you can use 5W-20 but to change it back at next change, or something along those lines I think

 

My Father is bugging me about going to thicker grade, so I thought I would ask. I used 10W-30 in my 2007 Tacoma for its whole life, but I am sure things have changed since it came out.
I was thinking about using Mobile 1 0W-20 Truck and SUV oil

 

Different engine. My suggestion is use what Toyota engineers suggest. It’s easy to find and cheap where there really is no positive to going to another grade.

 

You can use any viscosity of oil for an engines whole life, but that life may be much shorter than expected.

 

Thicker oil flows slower through the VVT screen retarding ignition timing. Use 0-20.

 

LOL good one.

 

You don’t need old school heavier oil. Newer engines are running tighter clearance for better fuel economy and believe it or not that thinner oil dissipates heat more readily. Toyota and everyone else went to these oils because they are better. Daddy needs to go over and read up at www.bobistheoilguy

 

Just because it's Friday,

Not all

$54 0W20 oil Toyota/ exxon mobil Case of 6 Quarts Full Synthetic TGMO SN 0W-20 Oil

0W20 oil is exactly the weight, some are 0W25 or heavier in voa.

 

Not gonna make much difference except when cold, that’s where the 0 weight first number will flow easier. After the engine warms up the second number comes int to play and they’re both the same at that point.

Viscosity is notated with the common "XW-XX." The number preceding the "W" rates the oil's flow at 0 degrees Fahrenheit (-17.8 degrees Celsius). The "W" stands for winter, not weight as many people think. The lower the number here, the less it thickens in the cold. So 5W-30 viscosity engine oil thickens less in the cold than a 10W-30, but more than a 0W-30. An engine in a colder climate, where motor oil tends to thicken because of lower temperatures, would benefit from 0W or 5W viscosity. A car in Death Valley would need a higher number to keep the oil from thinning out too much.

The second number after the "W" indicates the oil's viscosity measured at 212 degrees Fahrenheit (100 degrees Celsius). This number represents the oil's resistance to thinning at high temperatures. For example, 10W-30 oil will thin out at higher temperatures faster than 10W-40 will.

 

Ok, thanks guys. 0W-20 it will be.

 

A long time, 20ish years, I worked at a car dealership, in the parts department. While I was there, the newer models/engines that came around had changed their oil requirements. The older models had run on 10w30. The giant oil tank that fed all of the tech bays was stocked with 10W30. Gradually the newest 04/05/06 etc models were calling for 5w20. Even when the specs had changed to 5w30 (in the 90s), the orders for the tank fill never got updated. By 07 the specs were 5w20 and some even 0w20. After a few warranty issues trying to track down odd oil pressure issues, nothing catastrophic but lights and odd readings, corporate recommended that the giant tank start getting 5w20 and cars needing 0w20 got individual quarts.
After that no more odd pressure issues.

Will it blow up your motor, probably not. Does it work the oil pump more (literally reduce overall efficiency) and cause issues on tighter tolerance pathways and potential lead to "more" wear, most likely.

 

I run diesel fluid as well as diesel fuel in mine. I've been noticing a huge improvement on the low end torque

 

5W30 will be absolutely fine. Toyota recomends this weight for the 2GR-FKS on other continents.

 

Wat?

 

Sounds like my Dad. He's been using 10w-30 for probably past 30 years and you won't convince him otherwise. If the owners manual doesn't say its supported, don't use it. Some engines have a "recommended" weight but also list other weights but not this one.

Good luck with the conversation with Dad. I always try to bestow some newer knowledge but his stubbornness doesn't let him go beyond a certain point. Man I can't wait to be old(er).

 

I would use the recommended viscosity range myself. Having said that I don’t live in a cold climate so I wouldn’t shat my pants fearing engine early failure if I ran 5-30, the actual running viscosity is higher equivalent viscosity number than 0 with a warmed engine. And if I lived in a really hot climate I would probably run 5-30.

 

I use Mobil1 0W-30. Easy enough to find in big box stores.

 

You have to introduce new information to older parents slowly or their ears shut down and you get some long story. Sadly, I think I am starting to come down with the same condition.
