Rear End Gear Oil Change *THANKS EVERYONE*

YosemiteSteve · 11-16-2005, 03:24 PM

Hey a big thank you to everyone discussing the oil change on this site. I immediately bought the new cover and some oil and thought what the heck, might as well check the pumpkin...I'm so glad I did, anyone for grey metal filled gravy on your potato's???

It looks like the mess on the driveway cleaned up nice.

Used Royal Purple Sythetic 75W-90 think it was around just over 2 quarts.

You should have used 75w-140 syn. It states that on the new finned cover.

"Should" maybe, but not a requirement for a 2004 Titan, owners only. Here is a link to a Technical Service Bulletin, (TSB), about the specification change. It is addressed to the dealer service departments. The 2004 owners are not required to follow this, but the dealers, (instead of Nissan), will pay for a rear end if it ever goes out, and Nissan can prove that the dealer didn't follow it. If they had changed the wording and mailed this to the 2004 owners, Nissan would be required to pay for the gear oil and the labor too, if less than required change interval.

I still use a synthetic blend 80W90 in the front and rear per 2004 specification. It is Schaeffer 267 Supreme Gear Lube - 80W90.

I personally believe it is a better product. After driving country roads for an hour, I can crawl under the truck and grab it with my bare hands, and hold it. The only bad thing is you have to contact one of their local reps. to buy it, and then only by the case, 12-pak. It was about $85 including the shipping. I think you 2005 and 2006 guys are out of luck since they don't have an equivalent product in your specification's weight. And their full synthetics are sold by the drum.

When my nephew bought his cabin cruiser boat, which I would guess weighs between 4500 and 5500 pounds, I towed it for an hour and a half, and then up into the foothills. After about two or three minutes I remembered to check the rear differential temperature, and it was too hot to grab, but I could easily put my hand on it for 1 full second, (this was a 75F evening).

Since for 1 hr. of 55-60 mph normal driving, (60 F ambient), I can grab the OEM's steel cover and hold onto it without being burned, only warm, if any of you with steel covers and M1 or other full synthetics can try it and report back it would be interesting. [Lightly touch it first, before grabbing as it might be very hot].

But the egg-beater test on "bob is the oil guy .com" is what convinced me to try this product. The full synthetic doesn't climb, and the 267 is all over those teeth, (4th pic down. It also separates from water better than the full-synthetic they used in the comparison, pics 1-3.

Swarren - thanks for that neat link on the egg-beater! That would have sold me on that stuff.

Herbpov - as far as what I put in mine, I'm kind of with Swarren going on experience and driving habits, I have quite a bit of experience with this stuff over the last few years on the job, towing, frequent drives up and down mountains, along with family, friends and co-workers, everyone seems to have the best luck with this. It is very pricey and Royal Purple is about to raise prices the cheapest I've been able to find is on ebay from this seller who is wonderful, sounds corny but I ordered a few cases for my brothers as gifts = http://stores.ebay.com/KRP-Royal-Pur...toreviewQQtZkm. It's not whats stated on the fin next to the fill plug but like swarren points out, what the average owner at home does might be a little different, they do offer a 75w-140!

How much is the Schaeffer product? Do they make any other products? Thanks for that link, that was informative.

It was $85 for a case of 12 shipped to Cali.
They do make other stuff but most of it is only sold by the drum. Since I have a 2004, 80W90 GL5 is still spec. and since it keeps the differential so cool I will continue to use it.
