Daryl - Does that take a 5W30? The fac fill is Castrol I believe. They seem to be owning the market in Fac fills as of late - they put a big push into bulk oil selling and are offering it at cost to fill out the mfg.

Switching to a syn with a newer model is fine - years ago the seal technology would tend to produce leaks because of compatibility issue. That has been over come for the most part. The Toyota engine is so robust you will not have any issues. As for the oil chemistry, the new API specs have made the lube companies step up and really produce product that is better than it ever was. The chemistry is compatable now - years ago some real funky ***** was going down - not so much any more.

Truth - with the Toyota engine, you could have a camel spit into the crank for your lubricant and run it through a sand pit and the engine wouldn't blink. They are great trucks. The synthetic is fine and you should be able to go 10K to 15K between changes - send me your shipping address and which weight you need and I will hook yo arse up brotha!
