Ok so here is all the information, I have spent the last week or two reading (IH8MUD member) and reading. There are lots of debates on what to use but with my "antique" flat tappet cam engine, and basically I need something with a higher ZDDP%. From my reading, the original oil used for these was SF rated oils so the ZDDP should be AT LEAST 1200/1100 for zinc/phosphorous to simulate that.
Now I haven't picked up the truck yet so I don't know what the original OCI or product used in the engine was but it has almost no rust and has lived in SLC,UT almost all it's life, so I figure I will start thing off right with good oil and a low OCI with testing at Blackstone. I live in Northern Nevada so we get temp swings from single digits in the winter to triple digits in the summer.
1. 1985 Toyota Land Cruiser FJ60 (4.2L straight-6)
2. Originally SF rated, initially will start with 3k miles OCI
3. Carson City, NV (NV High Desert with Lake Tahoe in my backyard)
4. She's an FJ60 so she will not do more than 70mph! Easy driver and won't be going very fast with this thing.
5. Will mostly be a winter commute vehicle other than that she will be for dog hauling, mtb hauling, camping and the occasional fishing trip with fire road runs and some light wheeling.
6. No known issues. Will be replacing smog pump (no emission in my area or owners), leaky p/s pump and a few other odds-n-ends. Engine has approximately 175k with no rebuild.
With all this said, the reading I have been doing, and my analysts brain going full gear, I am thinking that my best bets for oil are going to be a 15W40 or 10W30 to cover the temp swings. Brands will be whatever I can get locally because I hate ordering stuff like this online. I know that I can get Rotella T/T6 and Delo 400 LE locally but wondering if there is something else I should look at (no Brad Penn or CAT DEO dealerships here). On top of that, what additive should I be using to up the ZDDP% or should I wait and do the first OCI and see how things are?
I appreciate the help and look forward to a long life with this truck.
