IS 250 Differential Oil

[Verbout]

Car passed its MOT the other day, the mechanic notice a noise in the differential when he spun the rear wheels, it’s something I’ve noticed but never done anything about.

A change of oil is called for as a starting point.

Where do you get LT 75W-85 GL-5 oil from?

Halfords stock something similar which is reasonably priced but I can’t find any that meets the exact specifications.

eBay?

Cheers Dave, I’ve looked at the Redline products, not cheap.

£43, and I’d need two. Thanks Nemesis,  I’d already found the expensive ones,    

I was looking for something more reasonably priced. 

[NemesisUK]

I wonder how much postage would be?

I'll pass on that as well.......:lol:

[Verbout]

Found some at Opie Oils, it helps if you miss off the first two letters of the code, the L and the T.    

£30 for 2 litres, including postage.

[NemesisUK]

I saw that but wondered if it was the same grade?

[Verbout]

It’s got all the same numbers and letters, 75W-85.

 GL-5 is mentioned in the specifications section.

It’s going in the diff as soon as I’ve finished decorating.

Here’s the link.

The 'LT' prefix may be important..

I believe it refers to Lexus/Toyota. Does anyone know different?

[Verbout]

I’ve sent an enquiry to Opie Ools regarding the letters.

The posts in the link seem to suggest 'LT' is for non-LSD equipped cars, 'LX' for those with LSD?

[Verbout]

The man at Opie thinks LT stands for Lifetime, but he’s doing a bit more research.

Yep, got that, sorry I didn’t notice the link, thanks.

According to the manual I have to get under the car, the diff should be labelled as to whether it’s an LSD or not. 

I would expect a non LSD.

[Verbout]

Just got the OK from Opie Oils, the oil I purchased is a replacement for the Lexus/Toyota stuff.

But they had to draw a blank on what LT means.    

[NemesisUK]

Just checked the service sheet from Lexus-tech.eu for both the RF300h and the RC-F

Just as the post in my link stated. Use the LT for standard or torque vectoring diffs and the LX for the LSD diff

[Verbout]

Right, my next question is:

If the change of oil does not quieten the diff, what are the collectives view on using an additive?

[NemesisUK]

The less scrupulous dealer might add some sawdust to the  oil to quieten a noisy diff 

How long do you expect to keep the car? An additive might be a short term solution but my preference would be to diagnose what the noise is. Might be simply a slight adjustment of the crown thrust bearing. 

[Verbout]

Haven’t heard the sawdust tale for a while, Arfur.   .

My car ownership is always long term. What I will do is try the oil change, see how that goes, then look into the internal’s of the diff’, I haven’t had one apart since the ‘70s.

Thanks for your input.

How often should the diff oil be changed? I had mine done but it was a while ago,

[LennyLexus]

Diff oil should be changed every 2 years or 20k and is included in the major service. I'm going indie for servicing from this year on labour only basis, but my mechanic will supply gulf diff oil for £12, can't beat that bulk purchase.
