Wrong weight - too heavy if you're following Honda specs.

My car had 75w90 GL-5 put in for it's first diff fluid change done during a service - can't remember the brand, but it did delay things - they didn't have any in the workshop/parts so had to send the parts van out to a local motor factors to get some.

It's a worry that some Honda dealers will take on S2000 servicing but don't stock the right diff oil isn't it!

Brian, what do you think of "Castrol Hypoy LS GL5 SAE 90 gear oil for limited slip differentials"? I may buy some of this in and supply it to the dealer to use in my next service (or do you think the 80-90 that they used last time would be better?)

I would be interested in your opinion.

Mike.

 

Just asked an oils specialist about this. This is his reply. You can contact him if you like.

Pete,

As far as I can tell the S2000 requires an EP80w-90 diff oil. the EP stands for extreme pressure. There are no other special requirements for it. Previous diifs may have failed if they were not using an EP diff oil.

Cheers

Simon.

Well - Honda UK have just called a few minutes ago, and confirmed exactly what I think we all knew already, which was that the s2000 requires Hypoid semisynthetic GL5/GL6 oil with a (viscocity rating ?) of 90. That's consistent with everything I've read and all the advice I've been given here. They also confirmed that Dual Pump fluid is for the CR-V, NOT for the s2000.

I mentioned that not only has my dealer put dual pump fluid into my diff, but that I have now encountered more than just a couple of similar cases experienced by other owners, which have resulted in noisy/damaged/broken diffs.

They do seem concerned about this, ("that's very odd" were the exact words) and have said that as a starting point they will contact my dealer , and that I can expect to hear from them again tomorrow morning. (We'll see ..........!)

Please keep us posted about this - it will be good if HUK do something about kicking their dealers up their collective backsides to improve their service on this particular car. Other importers, in the past I think, have only allowed small numbers of dealers to sign up to working on their "specialist cars" and set higher standards for them. I think that's what HUK should do with the S if they are serious about this car. Then, bad feedback from customers like this, and "three strikes and you're not selling or working on S2000's anymore my dear grease monkey". Dream on.......

 

Sorry - can't tell but will try to find out from the guy who did the work. He really does know his stuff so I'd be surprised if he went for something inappropriate. Diff has been quiet and all appears to work well. I've done about 4,000 miles since rebuild, so take this as a good sign, especially as the diff went wrong inside a week from being serviced and causing the problem in the first place

HondaUK just called, having questioned my dealer as to why they put dual pump fluid in the diff. Apparently, the dealer is now claiming that they used GL5 hypoid oil (the correct stuff).

Hmmm - so to recap - the invoice says they used Castrol Magnatec (engine oil)
When I phone them to check this they say 'no - actually we used dual pump fluid.'
When Honda UK call them, they say 'no - actually we used GL5 hypoid'.

Well, call me a cynic, but I do believe they're making it up as they go along. Somehow I don't think I'll be taking my car back there again - and meanwhile I'm still not sure what's in my diff. When it explodes all over the motorway I'll be sure to scoop up a sample.

I really get the feeling dealers are bunging in whatever they happen to have lying around. What do you think - is it worth putting my concerns in writing to my dealer and forwarding a duplicate to Honda UK, or would I be wasting my time?

 

If I were you I'd change the oil myself now for the correct spec (or get a trusted local garage to do it if you can't). The important thing is what oil is actually in that diff (not what oil the garage says is in there - how can you trust them now)? Don't tell anybody you have changed the oil and, if you should get any future problems, it won't predjudice your warrenty. However, if the wrong oil is in there now you could be avoiding anotehr diff failure.

If you do this I would also suggest keeping a sample of the old oil in a small bottle. For peace of mine you could get somebody to check if this seems to be the right oil (I'm not suggestting oil analysis but hypoid oil is quite distinctive and somebody experienced will be able to tell you if its hypoy or not).

Reliabilty and confidence in your car are the main thing IMO, and worth spending out on another oil change.

 

Now ask the same question about gearbox oil. Honda say Honda MTF - NOTHING else. OK, I would like to order 2 litres. Wait four weeks. Sorry cannot get it in litres (even though I supplied Honda part number). In the end my Honda agent gave me 2 litres drawn from their big 100 litre drum - which I am assured is MTF.
