The manual calls for a 0W-20 but states, "If SAE 0W-20 is not available, SAE 5W-20 may be used. However, it must be replaced with SAE 0W-20 at the next oil drain." Fairly straight forward. It then goes on with a little blurb explaining oil viscosity under which it says "The 20 in 0W-20 indicates the viscosity characteristic of the oil when the oil is at high temperature, An oil with a higher viscosity (one with a higher value) may be better suited if the vehicle is operated at high speeds, or under extreme load conditions."
Am I to take this to mean that Toyota thinks it's OK to use 0W-30? I own a small farm and this truck is going to be used as a light duty hauler, as well as my daily driver. Would driving around with a loaded bed, or towing trailers through hill country on occasion count as "extreme load conditions"? We do have a fairly long and hot summer here. I know the fine engineers at Toyota didn't call for a viscosity that would kill the engine, but I wonder what amount of wear they felt was acceptable in order to gain a few percentage points in fuel efficiency. If I run something other than a 0W-20, am I going to be putting my warranty in jeopardy? I also have 2 years of Toyota Care, and that's a lot of free 0W-20 TGMO and filters to pass up. A 0W-30, 5W-30 or 0W40 would certainly give me more peace of mind, but would it just be that? I suppose I could get some oil analyses done along the way and see for myself how well the 0W-20 holds up.
You can, I do. I run the heavier oil in the summer, and the free oil changes from Toyota care in the winter.
I just had my oil changed in both vehicles at different dealers. The Tacoma got 0w20 in Galveston, in Boerne I had the oil changed in the 4 runner, it got 5w30.
Both vehicles will get a 30 or 40 wt in the spring. Once Toyota care is used up I will probably run a solid 30-40 wt for year long 10k OCIs. I will do a performance cheack at 30-40k miles with a used oil analysis. don't mind using whatever the dealer has in the cooler months for the shorter for now service intervals.
Keep in mind if you are pulling trailers, or doing a bit of ranch/ farm work..you should probably use the severe service schedule anyway. My vehicles either get exposed to oilfield off road heavy dust and rough roads, or idling, city traffic.
Use the free services for sure,
At 5k, I just drop the plug and drain the sump and add 6 qts or so for the extra service, you can take it in to the dealer (I do less waste for me to deal with)and they will do this for you, you can bring your own oil or simply ask for their synthetic 5w30, they never even charge me to do this while they rotate tires and top of the wiper fluid and do their inspections for the every 5k service. No need to change the filter, let the dealer do that at 10k/1year.
