Also on a side note is anyone running synthetic ATF?

It is a h### of alot better than $300 the dealer charges, but I am still concerned about warranty issues. What other manufacturers are there that someone else on the forum is using??
The service guy at the tranny shop said that GM 4X4 setups, depending on the system, did not recommend using synthetic in the transfer case. Has anyone else heard anything along those lines?
Geeeeeze, It seems like this stuff is liquid gold. You get the right combination of magic sytnthetic elixir and your truck might run forever!!But screw up and you may be in a big pile of sheep sh@# when it may void your warranty..............decissions, decissions.

anybody remember when HP TV changed the new Z-28 to all synthetic (engine, tranny, rear) and gained 10rwhp on the dyno? They used Royal Purple.
The factory lubricant used , for 2001, is GM part # 1052271Doogy wrote:The GM part number I previously provide is for GM's synthetic diff fluid but I am not sure if that is what they provide from factory.........I doubt it.
I am unfamiliar with Mobil 1, but if it meets or exceeds the API GL-4 spec. I don't see a problem. To be safe, since service departments tend to vary, I'd call a couple shops that are close (where you would go for warranty service) and ask them. Document the person to whom you spoke and date. That should cover yourselfExMoparMan wrote:I am wanting to change to Mobil 1 but have been hesitant without knowing #1 if it will void the warrenty #2 not cause wear or effect the operation of the rear end parts.

As for the effects. I can't see how it would cause harm if it meets the requirements , but it may behave differently. You can be the "Guinea pig"
Summit carries Red Line & Royal Purple. Both are good brands. Amsoil is another if you can find a distributor. Dexron III for the tranny and transfer case, 80W/90 front and rear diff. I am using Mobile 1 syn. oil for the engine, Redline Heavy Shockproof gear oil in front & rear diffs, & Redline High Temp ATF in the transfer case. The Heavy Shockproof gear oil I run is way overkill, but I was told by Red Line that it would work fine for my application. I think they have a 75W90NS that is closer to the stock rating. I run regular ATF in my tranny because of several tranny failures in other cars I've had directly related to using synthetic ATF.f9k9 wrote:What brands and weights for the tranny and transaxle should I look for?

So what do you think of their new 15k mile oil? I remember years ago that an old Amsoil dealer here in Napa told me that they made a motor oil that could go that long before a change.Ken wrote:Mobil 1 is a pretty good product I just hate the fact that they have been robbing their customers for years with the 3months/3000 mentality here in the U.S. While endorsing extended drains overseas.
I beleive that the New Mobil1 15,000 mile product is a Full Group IV, I'm fairly sure that the New 5,000 and 7,500 mile oils are Group III.So what do you think of their new 15k mile oil? I remember years ago that an old Amsoil dealer here in Napa told me that they made a motor oil that could go that long before a change.What do you think? Is this true? I was also wondering if Redline and Royal Purple are group IV Synthetics? What kind of pricing do you offer on Amsoil products? Sorry for so many ?'s.

These mileage #'s are amazing! Do you have to use Amsoil filters, or would the use of K&N or other oil filters be ok? What is the micron filtering rating for the Amsoil filters? Is there any way of getting an Amsoil catalog? I would pay for one if neccessary. Thanks for the info.Ken wrote:AMSOIL has products that are rated for 1 year/25,000 miles as well as a 1 year / 35,000 miles. Using their filters and changing the filter every 6 months or 12,500 miles.

That report has some interesting information but looks a little dated "last updated 05/25/99"
Here are some more resent test results on the SAE HS 806 test
TIME WEIGHTED EFFICIENCY
WIX PRO-TEC 101= 69.3 %
AC PF-2 = 75.89 %
FRAM DEFENSE DL5851= 80.15 %
FRAM PH8A = 82.03 %
WIX 51515 = 83.96 %
HARD DRIVER HD-01 = 85.87 %
PUROLATOR L30001 = 86.00 %
PURE ONE PL3001 = 91.56 %
AMSOIL SDF-15 = 94.23 %
CAPACITY IN GRAMS
WIX PRO-TEC 101 = 6.38
FRAM PH8A = 8.17
FRAM DEFENSE DL5851 = 11.21
PUROLATOR L30001 = 11.42
PURE ONE PL3001 = 11.64
AC PF-2 = 13.26
WIX 51515 = 13.46
HARD DRIVER HD-01 = 16.95
AMSOIL SDF-15 = 18.19
The HS 806 test reviews the ability of a filter to remove a known contaminate from the fluid stream over a period of time. Results are reported as the percent of contaminant by (weight) removed over a period of time (Time Weighted Efficiency). Capacity (life) is also determined by noting the amount of contaminant required to increase the resistance across the media a given degree. Capacity is reported in grams of contaminant (Capacity in Grams).
Don't confuse the SAE HS 806 test as rating on contaminant size. It has nothing to do with "mircon" rating that is a different test. The SAE J1858 test is used to rate the "mircon" of a filter.
