gear oil

I know this has been talked about a lot on this forum but need it in laymans terms lol .
2015 trd 30000 mile service mainly on road use pull a camper occasionally can the differential change wait longer ? looking up specs it calls for lt 75/85 gl5 or equivalent front and rear . then for transfer case says 75/90 . what can I use that wont break the bank that meets these specs . can u used the same oil in all 3 and what would u recommend ? according to aldata it just says to inspect and spark plugs (and routine maintenance ) but you talk to a dealer and they recommend to do way more . most other manufactures don't even service these things until 100,000 or they are non serveicable. .
going to be installing a leveling kit and some new sneakers here the next oil change

 

You can use 75w90 in both diffs and the tcase. On my 2008 , I went 50,000 miles before servicing those items, but not everybody's situation is the same. I never towed or hauled heavy loads and my off road use was minimal. BTW, welcome to TW!

 

plain jane or you think synthetic is the way to go ? on the 15 I don't need to ad any additives correct ?

 

you could most likely push the gear oil back out to 40k, but wouldn't hurt to open the fill plug and get a small sample to make sure the oil isn't watered down.

As for the plugs, depends on what engine your running. 4.0 recommends to be changed at 30k, 2.7 recommends to be changed at 100-120k. either way, still doesn't hurt to pull a few and check them out.

 

No additives are needed, but I think 75w90 is only available as a synthetic so it won't be cheap.

 

thank guys I'm thinking I will push it till maybe the next oil change do plugs now they are cheap enough little tight on cash with Christmas and the new tires . the neighbor down the road has a taco with 300000 plus miles on it and he told me the only thing he has done is brakes oil tires exhaust rack and wheelbearings he said he never has changed a drop of fluid . so it make you wonder if sometimes we get alittle crazy with the maintenance

 

You'll be fine. 30k is nothing for modern synthetic gear oils. Change it when it is convenient for you.

 

I used REDLINE 75W85 in the rear only from EBAY, and used Walmart super tech 75w90 in front diff and transfer both are GL5, most people are using Valvoline 75w90 full syn in all 3 from what I have read its a lighter weight 75w90 and close to the viscosity index of a 75w85

 

I've heard mixed reviews on Redline. I used Lucas Synthetic 75w90 on my Prerunner with the locker. Some say certain brands will cause chatter if you have the locker. Lucas has worked for me, but oil is oil. I say as long as you change it and don't opt with a cheap brand OP will be just fine.

 

why did you choose to do the 77/85 just in the rear ? cost?

 

only reason I used redline was it was rec,d by the manufacturer weight and was the most cost effective, as far as Super tech was a semi synthetic 75w90 gl5 I used in the 4x4 components cause I really don't use the 4x4 a lot to be honest wasn't worth getting the finest oil

 

rec,d by TOYOTA for my truck 2013 sr5=75w85 front and rear diffs

 

if your pulling a camper probably better using a 75w90 gl5 in the rear its slighty thicker at different temps then 75w85

 

http://www.ebay.com/itm/REDLINE-501...ash=item28164b74a9:g:YrwAAOSwNyFWdysl&vxp=mtr I used this in the rear only best price

 

ECGS recommends Lucas Dino 85w140 in diffs front and rear

I do a 75/25 mix of 85w140/75w90

 

Mobil 1 75/90 GL5 Synthetic @ 50k intervals for all 3 components, based on your use pattern. There is no reason to use any boutique lubricant, OTC is just fine.

Available at WalMart and other bargain outlets, look for a sale.

Personally I'd forget any 'level lift' nonsense and apply the funds to regular maintenance.

Yea, the guy down the street has 300k, but it doesn't mean you shouldn't ignore him.

 

Redline makes a 75-110 GL5 that is perfect for these trucks in the diffs. I use Redline MT-90 GL4 in the T-case and transmission (6spd). I have settled on changing all the fluids when I buy new tires. That is 40-45k, and it just makes it easier to remember. I installed a temp sensor in my read diff to monitor heating while towing. It has taught me a lot! I've tried a number of different lubes in these rear diffs, but Redline gave me the best performance. Amsoil severe gear was also good in the diffs. The rest were back in the pack. These little diffs in the Tacoma really take a beating, so I would not cut corners on lube! Temps can reach 220+ degrees easily pulling a trailer.

 

I've used AMSOIL Severe Gear lube in both diffs. since changing both at 100K. Did another drain and refill of both at 200K. At 329K now and letting it marinate a little longer this time.... Claims it has the needed properties for a limited slip rear so you won't need the additional gear additive that a typ. limited slip rear needs. Found that not to be the case and have always put in a new tube of their SlipLock when changing the rear fluid.

 

I plan to do it here most likely within the next 5000 miles . That's y I'm asking the question . If I can get away with 75/90 in all 3 . Or does it need to be thinner in the front diff? I have access to 7590 that says it exceeds gl5 .
