Newbie with a 2006 Land Cruiser and Qs

[Kanaljen]

Greetings all!
Just got myself a 2006 Land Cruiser with only 11k miles on it!
My first Q for this forum is about maintenance.
I think I read somewhere that the LC should have all oils changed at 15k.
Well, Im almost there and I want to go over and change all the oils to the best and know that it was done right.. (the dealer said that it was all taken care of but... piece of mind is worth a lot...)
Thinking about Mobil 1 5W-30 for the engine and Redline AT for the tranny. I guess some thicker and fitting Red line for the diff too..

In addition to my Qs about oil and maintenance, can some LC fellow tell me about rim and tire sizes too? Looking to have a 2nd set of rims and agressive tires for my days in the sand dunes (Pismo mainly) and deep snow (snowed-in Sierra trails)
I think I have 275/60/18 right now (think it's stock) and look for something that can be aired down to get a big fat footprint. Maybe 16" inch rim with something very wide with a tall side wall and agressive tread..
Any suggestions? What would fit even if I lower the LC to the lowest suspension setting? I would like to be able to drive on the freeway etc TO Pismo and the mountains so it can't be too off-roady..
Thanks!

Do you have the owner's manual or maintenance guide? If not, here's an excerpt:




For the ATF, you would need to do a fluid exchange or a Rodney flush (search for this).

Would you mind sharing your location?

Thanks for the info!

What type of oil is recommended?
I have order a repair and maintenance CD so the DYI should be in there.

Any recommendatiions about wheels and tires too?
Need a set form my days at Pismo (sand dune) and preferably somehting that I can put on when I head for the mountains and desert too.

What the biggest that you can get on there without rubbing when set in the lowest suspension mode?


I'm in sunny San Diego!

The vehicle has only 11k miles...just change the oil with a quality synthetic and go 8k to 12k between oil changes...but occasionally check the oil level. Also, I would really reconsider doing anything to the tranny until at least 50k...then do a drain-n-fill with Toyota stuff. The diffs still have Toyota's factory gear oil and should stay that way for at least another 25k miles...IMHO

Would Mobil 1 5w-30 or 5W-30 SUV be the "best" choice?

I think the 15k maintenance calls for changing the front and rear diff oil if you tow...

Since I don't know what engine oil is in there and since I don't know how hard the car has been driven, I thought about duing the 15k now and get the best synthetic in there!

Would you recommend to use M1 for engine but maybe just stick with OEM for the diffs?

How do I know if my diffs are open or limited slip?
