Just wanted to report that I finally got the diff. fluid changed. I wasn't there when they did it, but they guy who did the work told me the magnet was fuzzy with metal shavings. Glad to have that out.

I paid $30 for two quarts of Amsoil Severe Gear and $21 for the labor.

I went to the local autoparts store to look for my mobil 1 75w-90w gear oil for my differential. Well I didn't find the exact gear oil but I can across royal purple. I remembered someone mentioned it here on camaro5.

What are you guy/gals using for your differential lube? Give me you opinions and why? What am I looking for on the bottle?

Same for the motor oil. I went to get my 8 quarts of 5w30 and got confused. If I get mobil 1 synthetic 5w30 am I covered or am I supposed to look for something else on the bottle??

Mobil 1 Engine......Mobil 1 Synthetic Tranny...... Royal Purple Diff....
Since I did the tranny and Diff I've documented an increase in my Mileage. Prior to tranny and diff I was getting avg of 17.5/17.7.

Last 4 tanks have been:
(18.4/18.7) Tranny fluid change
(20.44/19.4) Diff Fluid change

Based upon my records it is helping out too!!!

Anyway, I've been talking to my mechanic friend about getting the differential oil changed. He recommended some BMW M3 gear oil that he said is top of the line stuff. Unfortunately he was out of it this week. Talked to him about Royal Purple, Redline and Amsoil. He liked Amsoil, but doesn't stock it. Can't find anyone else in town who does. He hesitated on the other two only because they would be obvious if the dealer ever drained the diff. and I'm not sure either one is approved for a car under warranty. Not that it should really matter, but I don't care enough about either product to even want to argue about it down the line. Anyone know?

Talked to a guy at my local auto shop today and he pointed out that Royal Purple does not advertise itself as "full synthetic" unlike Mobil 1 and Redline. Apparently, this indicates that RP is a blend of synthetic and non-synthetic. Given that's it's also the most pricey, I'm probably not going with that.

What my guy does have in stock is Total brand 75w90 which is made by Elf. I've not heard much about it but at the moment it's looking like that's what I'll be getting sometime tomorrow.

Curious about the M3 gear oil

Edit- ran over to the Bimmer forums and its tha same as over here... RP or Redline

They seem kinda racist with Mobil

I can echo that with mine although I went with RP for everything; engine, trans and diff. Does your car seem to coast easier and farther now? I noticed it when I put it in neutral especially the car just seems to glide along easier.

Surprising you ask that. Yes, Yes it does. I even was "boasting" about that to my friend who has an EVO. I can usually gain several MPH increase on mild grade hills just by coasting in neutral. On a flat strech I can coast with a drop in mph of around 1 mph per 1/4 to 1/3 mile or so. (guess here but fairly close).

All you guys need to be carefull with royal purple, on turbocharged cars we hate it, RP brakes down way to quick their fluids for some reason are very well marketed and advertised for the honda civic rice burners.
But its not giving your engine and drivetrain the best of whats needed, i preffer to put autozone brand oil before i use that brand,,,

you want an oil that will hold up to heat and high torque applications, specially if you are running any type of boost from a turbo or supercharger, compressed air puts extra heat in the motor , dont give your engine the least of the good as far as its blood goes.

Enough of talking, now lets talk about real data what matters, there is plenty ASTM, and many other test that goes into oils out there and i say AMSOIL hands down has done very welll stacked up to other brands, i have a few Evo's that are pushing 30 lbs turbocharged at around 500AWHP and i tell you what nothing else cooks an oil than high boos and high horse power.

here are some links that might help you guys with educating on what oil is best for your 30K plus machine.

This link has it all in it, NOAK testing, Four ball wear test, ect... you guys can pm me if you have specific questions on what fluid should your, tranny, brakes, motor and diff. http://www.amsoil.com/comparison/motor-oil.aspx

FastOil · 05-08-2010, 04:56 PM

Yes and i have respect for these Evo's they are stupid fun to drive and they are beastie when moded, they have an incredible stout bottom end, they have the 4G63 with a cast iron bottom end that can handle stupid amount of boost,,,, well i dont want to take this off topic but the point is good oil is being used by good well known shop all over the nation, cars that are being put through their paces.

It's ALWAYS an Amsoil advocate that "warns" against RP, ALWAYS. And they always link to an Amsoil page as "proof". Mazda racing teams use RP with no problems. I've used it for years with great results. I'm sure Amsoil is a fine product. I will continue to use RP because my experience with it has been nothing but good, and I've heard nothing but good from others who use it. It's only Amsoil advocates who seem to have a problem with it.

its always the one person who has educated themselves and that has seen many oil analysis lab reports, and has seen what RP can do and what does not do,,,

have you ever seen a report on RP after 1000 miles,, once you do come back and report to this community with the suprise you will have for yourself.

there are plenty good synthetic fluids out there but thats not one of them.

ima not trying to tell you what you need to use but it is what it is and the data has proven it, and then when you open an engine up you realize that what the data was saying about the oil was true
