I’m checking in after I roll over 20k and wanted to see if there was any maintenance outside of what is listed in the FSM that y’all with a few more miles wished you would’ve done.
For instance I’ve been doing oil changes every 5K, and actually switched to PUP 5w30 at 20k.
I’m also considering changing my diffs and TC at 30K as well.
Do y’all have any other recommendations?
+1 on changing both diff's and tcase at 30k (or before for diff's - your call). PUP is solid, readily available oil. I am NOT concerned with 10k OCI, as the oil/filter combo I use are supposed to go much longer than 10k. But to each his own! You cannot go wrong with a 5k OCI imho irrespective of whatever quality oil filter you use, but I am assuming Toyota OEM.
I used the magic 75W toyota fluid and will be using my last two cans in a couple months at 60k, then who knows? It is definitely spendy and others who have changed are not seeing their Tcase grenade so far.
As
@bloc mentioned, the PSF is often neglected. I drain and fill mine every oil change and you can appreciate a slight difference in color in old vs new. If you're a disciple of CCN, he says the idemitsu PSF is what Toyota uses from the factory. It looks the same to me, but I am not planning on sending off samples to confirm. It's also cheaper than most trans fluids IIRC. Again, to each their own!
I also drained and filled my coolant at 50k. Yes, I know - it's early. Gave me the warm and fuzzies just like doing a complete fluid swap on my tranny without dropping the pan or changing the filter. I plan on keeping this truck for a LONG time and maintain it as such. I skipped the engine drain bolts (gasp - clutches pearls), and simply drained and filled the radiator a 3-4 times (iirc) at the petcock after letting the new stuff cycle with engine at temp (open thermostat). I figured this was a cleaner option for me as I have seen first hand what dogs look like after getting into coolant. Please keep your animals away when doing this - just in case.
Air filters to me are an easy win. I use Toyota OEM for cabin/engine and they get replaced annually with the cabin filter going every 6 months. Annual cleaning of the MAF can help get you an extra 0.0000001 mpg too! A penny earned, aM i RiGhT?!?
Brake fluid every 2 years for me - again, likely early as most do it every 3 years irrespective of mileage. Brake fluid effectively has a shelf life determined by time (for most) and not mileage. We aren't going for lap times in these BUFF's.
You're off to a great start and this forum has taught me a TON! Keep your nose to the screen and search for issues/questions/solutions/experience others have had and posted. Mud is a GREAT resource.
EDIT: My (so far) pavement princess is wrapped on the front with XPEL PPF and I did Gtechniq ceramic coating with a couple of their products both when new and just reapplied their EXO. Anyways, it's spendy but if you're going to DIY they make good stuff.
