Rear differential fluid

Hi,
The manual says I suppose to use "Toyota Genuine Differential Fluid gear oil LT 75w85 GL-5 or equivalent"

Can anyone recommend equivalent differential fluid please for 2015 pre-runner RWD 4cyl double cab?

Thank you all!

 

Go to the parts store.

Pick a name brand on sale. (Mobil 1, Valvoline, etc.)

Don't waste money on a boutique lubricant. (amsoil, Redline, Royal Purple, etc.)

 

Hi,
I like Mobile 1 too, but when the mobil 1 website does not recommend their gear oil for Tacoma when you select the vehicle by year and model on mobil 1 web site

 

does it matter if I put limited slip oil in non-limited-slip differential?

 

Just make sure it has the GL-5 designation on it, the brand is your preference.

 

It won't matter. They almost all say LS compatible, and most aren't anyway. The two most important items are GL-5 and full synthetic. If you use your truck hard for hauling or towing, then I would use Amsoil Severe gear, Or Redline 75/110 GL-5. The Tacoma has a 4 cyclinder ring and pinion. It generates a ton of heat in a 4.0 liter truck. The synthetic oil helps keep that temp down. On a heavily used truck, you will need a higher viscosity to handle the additional heat. If your use is normal, then any good synthetic, like Mobil 1 is fine.

 

Thank you! i drove a lot..already 90k miles in 2 years! it's 2.7 L pr-runner RWD. Per manual, suppose to change rear differential every 15k miles under heavy use! i don't tow but 50% of time the bed is loaded ! so, i think

$30 Mobil 1 75w90 Mobil 1 104361 75W-90 Synthetic Gear Lube - 1 Quart (Pack of 2)

Mobil 1 75w90 will be economical and meet the need if i change every 15k miles per recommendation.

 

yeah, amsoil is the no.1 , AND mobil 1 is FAR 2nd per these tests:

I've done my own tests using heat build up as the measure. First I used an infrared thermometer, then I installed a temperature probe in the rear diff. Amsoil and Redline were the best. The biggest difference was between synthetic and dino oil. I didn't realize the OP was running a 2.7 though. The load on his diff will be much more manageable because it is handling less HP. If you have an IR thermometer, try pulling a good hill on a hot day, and then quickly pull over and measure the diff temp. If you are over 220 degrees, I would consider a premium oil.

 

Amsoil Severe Gear 75W-90.

 

You're the best @Clearwater Bill . You're always trying to save ppl money, make them think twice about mods they don't really need, going against the grain constantly here. You're like a Christmas miracle

 

is there going to be significant MPG / fuel efficiency different between 75w85 vs 75w90?? considering i drive about 40k miles a year

 

No. I see a difference using 75/140, especially in winter, but you won't see anything between 75/85 and 75/90

 

A little revitalization on this thread... looking up my 07 Tacoma SR5 4x4 V6 the vin search says I have LS - so yippy I guess. Dont think it was standard on the SR5. Anyway, I'm going to swap all my fluids and picking an oil for diffs and xfer case. I have 190K on it - I did these back at 130K. Maybe I did them once since but can't remember. Anyway always had them done by a shop so they used Toyota fluids but I was planning on using Red Line.

Then (while writing this post) I switched to Amsol FGRQT (long life). Why? Because at 'member pricing' if you order 8 (to get free shipping) its $13.35/qt including the $10 member fee.
Note Severe Gear is $15.15 if you wanna go that route. Best I see on Mobil 1 57905 is about the same as Red Line and maybe saves $1/qt ($50/gal but no membership fees - qt's are higher)

Just thought I'd share my findings for those in need.

 

if you have a LS your supposed to use regular Dino oil with an LSD friction enhancer, also there should be a sticker on your differential that says LSD, or you could do a brake burn and see if you lay down twin strips.I was under the impression only the sport models had LSD's but nothing would surprise me

 

iv used mobil 1 .............. redline either without failure

redline has the latest selection tho i have to order
rather than buy off shelf

check & fill once a year

the ' LS ' limited slip factor has more to do with rear diffs with clutch packs

 

Well, the VIN search says it was added but I just had it up in the air and them wheels counter-rotate.
