What Motor Oil Do You Use In The 4.0L & 2.7L 2nd Gen.

Conventional - Synthetic Blend - Full Synthetic?
What Velocity - 0w20 - 0w30 - 5w30 - 10w30 - 10w40 - 20w50.

Here in the Southeast Region The V6 comes with conventional - 5w30 & 4cyl comes with 0x20 synthetic oil. I'm curious to see how many owners across the globe switch to the synthetic oil with the V6.

 

The 2.7 owners manual and oil fill cap call for 0-20w full syn. That's what I use.

 

Havoline synthetic 5w30

 

Generally Mobil1 Synthetic 0w-30 for me.

 

kendall synth 5w30 for my 4.0

 

Mobil 1 full synthetic 5w30 for my V6

 

What brand oil does the dealer use during the free oil changes?

 

Amsoil 5w30 in the v6 is what use

 

Some speculate its Mobil 1, but know one knows for sure. Probably the cheapest oil they can get there hands on.

 

I'd use Amsoil if I could afford it. Love that stuff

 

My dealer uses Toyota motor oil in the quart jugs.

 

I like my Pennzoil. Literally the ONLY brand of oil I've ever bought in 43 years of driving. I'm using 5/30 conventional.

 

CarQuest Full Synthetic 5w30 ( Valvoline syn in a generic CQ bottle ) $5 a quart easy to find ( until Advance Auto Corp phases out all the CarQuests )

 

5W30 Mobil 1

V6 with 115,000 miles so far

 

if they are a legit Toyota authorized dealer, they HAVE TO use what Toyota specifies, and 0w20 Mobil 1 is what the 4cyl cars and trucks use now. and 5w30 in the larger engines. Its an EPA and Emissions thing, they (Toyota) have to spec XXX for emissions purposes to achieve the EPA rating.

working for Toyota Industrial, we have to do the same thing, all the new lift trucks are spec'd for 10w30 Mobil DX 1300, where we were using 15w40 Mobil XD before. LP, gas or Diesel.

being a Toyota Industrial dealer, we have to do what they say for warranty purposes. have to use the Toyota Red coolant, and Mobil spec lubes in everything. and yes, they ( Toyota Corperate ) does check, even our service vans, I have to have a minimum stock of Toyota filters and specified lubricants.

 

I run Mobil 1 full syn 0w-30 in my v6.... No point to run 5w-30 full syn when there are 0w-30 full syn for the same price. 0w is STILL to thick at 100*f to properly lube an engine, but its A LOT less thick than 5w at the same cold starting temps.

 

I only use 100% Pure, Organic, Conventional Bacon Grease.



I've only had one oil change on my 2015 so far. Let Toyota do it for free. So I'm just assuming it's the "Toyota" 5W-30 conventional stuff.

 

I usually use .308... a happy medium of around 2700 fps

 

I appreciate al the feed back so far. There a lot of opinions about changing the TYPE of oil that the truck was born with and how soon you should do it. I'm running 5w30 convental oil and I have low mileage and I'm trying to decide whether to go to synthetic and when. Thanks again.

 

Only negative thing I've ever heard about switching to full synthetic had to do with it being more expensive. Can't recall hearing anything that was truly bad about doing it. Someone directed me to "Bob is the Oil Guy" some months ago. It's a long, somewhat dry, read if you're interested. What I took away from it was this: All motor oil has virtually the same viscosity once at running temperature. However, the point of synthetic is to reduce viscosity at start-up and warm up when the engine endures it's most friction and fatigue.
