No, sorry for the misquote. I was replying to wisconson's."The biggest advantage of using synthetics is extending your OCI (oil change interval). if you are using a synthetic, and changing your oil every 3000-5000 miles, that's a waste, and not necessary. I had a UOA done of valvoline synpower synthetic done at just short of 10,000 miles, and the report said I had oil life left and that it was properly protecting the car. So on synthetic I was changing the oil every 10,000 miles. I don't track my car often (i do run both 1/4 mile and actual road course occasionally), but I do drive my car fairly hard".

so....whats better, dot 3 or dot 4 for my 2001, for the brakes and clutch??

DOT4, its pretty much the same as 3 except for a higher boiling-point.

Some corrections:

1) LE-607 is GL-5 rated. Honda cannot refuse a warranty claim based on use of this lubricant.

2) LE-607 is not for arctic use, but it has a rated PP (pour point) of -11 degF. That is the lowest PP I have seen for a 90w gear oil.

3) DOT3 and DOT4 are not identical. DOT4 uses different additives - borate esters as I recall. Honda specs DOT3.

Other comments:

1) I recommend Motorcraft Super Premium DOT3 brake fluid if you want to stick with a long-life, DOT3 spec type. It has very high dry and wet boiling points. This is a terrific and inexpensive product, and an excellent choice for the clutch - I just flushed and refilled with this for my car.

2) DOT4 fluids almost always have higher dry BP's, good wet BP's, but tend to need to be changed more often than DOT3. I would not go much beyond 2 years with ANY DOT4. I use Ate Super Blue.

3) I have to laugh when I see "synthetic" brake fluids - they are all "synthetic". Glycols are synthesized - they do not exist in raw, unprocessed form.

Honda specifies in our owners manuals to use a SAE 90 hyploid type GL-5 gear oil in our differential (plain and simple). I have yet to find a bottle of gear oil that specifically states this exact wording on the product. The only thing that comes close to being the right product from my experience is LE 607 if you include the MSDS to clarify API rating. Now if you live in a moderate to warm climate, if think you have a better chance of being denied a warranty claim if you use a multi-vis gear lube with GL-5 written all over the bottle than you would using a straight SAE 90W without GL-5 written on the bottle. If Honda does try to deny a claim because you used LE 607 in your diff, ask them to see their SAE 90 GL-5 that you should have used.

that's because the the bottles that say 90w hypoid gl-5 gear oil are for honda motorcycles.

by the way, 75w90 is fine to use as long as it's GL5.

I've been hearing lately that Honda has a new Tranny fluid that is suppose to be better than the original. Has anybody used it? I tried search but found nothing on it.

Its part number 08798-9031

It's nice to see road rage stick his nose in here.

I changed over to mtl-p in my tranny after reading one of his reviews.

It's very slippery stuff. I'm happy with it but I wondered if anyone else has had any longer term experience.

Thanks

I'm using the new stuff right now. I've tried three other transmission fluids besides the new MTF, I like the new MTF the most for the following reasons.

1) won't void your warranty as it comes from a bottle with Honda's name on it

2) To me, this stuff feels the same as GMSMFM. That is, it feels much better than the old Honda MTF when the transmission is cold. When warmed up, it feels smooth and gives consistent shift feel.

3) So far it doesn't seem to be breaking down. GMSMFM was notorious for feeling "notchy" after 5-10k miles. I have almost 1500 miles on the fluid now and haven't noticed the notchiness that was already starting to happen with GMSMFM at the same mileage.

4) It's cheap! Two quarts cost me roughly $10, compare that to the $10 per quart price of the GM stuff and it's a relative bargain. I also had a difficult time finding the GM fluid, all the dealers I went to were out of stock (I ended up buying the last two quarts at a dealership that was 25 miles away from me). Compare this to the availability of Honda MTF, it's everywhere.
