im considering the 75w-110 too, run 75w-90 right now with a cusco 1.5 way in theback

 

Thats the smart way of doing personal life business, research !

Yep i hear ya,, the issue is we mostly reccomend 90, unless we have a special request from someone with high power and crazy driving habits,, there are a few out there using it and that are going to be using it.

 

I'm running AMSOIL in the t.case and rear diff. I love it and will keep using it in the future.

 

Waking up this thread for folds that want to learn about the different type of diff and TC fluids

 

I've got a built 2.4 and I'll be around 460whp or so. It's a DD and I'll occasionally take it to the track. There's some great info here by the way. Would you recommend the SVT 75w110

 

I did reply to your pm, with that power i would reccomend SVG 75W90

 

After reading all of this I am going to give the 75w-90 a shot! Use the Amsoil Motor Oil all the time, but usually Redline for the TC and Diff. We shall see if there is a difference. Thanks for the info guys!

 

amsoils synthetics are good at what they do and synthetics in nature are superior to "cheap" oils period. To question that is to question technology. is an intel chip from 1994 faster than the i7 chip in 2011? not by a long shot. tons of money and research are performed to improve oils and lubrication and not just in cars, but other industries. And lubrication is far more complex than many can fathom. is amsoil the best etc, decide that for yourself and your own feelings and listen to the graphs, charts and firm results from vendors.

Apagan,

dont waste your time explaining amsoil effectiveness to nonbelievers. The chemical research and development and understanding of synthetics is far beyond the scope of this thread and should be continued in a chemical engineering lab not here. and if anybody wants to come in here debating amsoils quality or other quality synthetic oil "effectiviness" must have good understanding of chemical engineering principles to properly debate. why? because you're talking about chemical structures, reactions, bonding etc. and influencing lubrication, etc on them. So saying random things about how its bad is invalid in my eyes without concrete scientific proof.

Drag passes etc help show that oil starvation is not occuring and since lubricated well working well for the owner. loud metal grinding and noises would also indicate poor lubrication etc. Surely tq kills drivetrain but to just say oil has no use but to lube two pieces of metal doesn't show much brilliance.

75w90 should serve you fine! pardon the rant

ps. my respect for the engineering behind these synthetics and lubrication is because my friend is in the industry and just does this. and i never knew what went into design and testing of such things.

thanks

 

Yeah sorry about the double question. I had actually asked in here like 30 minutes before you pm'd me, where I asked the same question. Thanks for the info.

Broham, you are absolutely correct in your response to this thread and the lamens that continue to bash oils, lubricants, viscosities, etc. without actually knowing a damn thing about chemical makeup of such things. I sat through hundreds of threads with comparison tests, uoa's etc, and I am barely scratching the surface of what actually goes into testing all of these. That's why I didn't have any input to begin with. I just asked the Master, haha.

I for one have seen what Amsoil can do. I have a buddy of mine that was running regular ole' Amsoil 10w30 in his 89 Silverado with a fully built stroker in it. One day he "lost" his oil plug and drained all of his oil out between home and work, about a 45min drive. Then turned around and drove all the way back, still without knowing. That weekend he was under his truck putting up an exhaust and found he was missing the drain plug. Now I fully believe that the use of Amsoil for over 30k miles in his truck is what saved his truck that day. The properties in the Amsoil's lubrication are well beyond my knowledge but I can tell you that all hell would have broken loose had he been using a different oil all that time and this happened.

 

You sir actually have some super valid points, i dont think it could have been explainned any better.

Technolgy has advanced very much, oil has improved with the technology these days, there is still many folks that say the good ole perto oil has worked for 20yrs in my car so why would i change it, but they are missing the boat big time, and missing out on less friction=more power and better gas milleage, cleaner engine ect ect..

Broham, i willl continue to try and educate this community and will try and do it with statistical data, real life data through the evo's we sponsor and run the fluids at the Time attack event.
In the past 3+ yrs we have had an astronomical amount of evo's changing their oils from many other brands to ASMOIL from the egine all the way to the rear diff and brakes,,, the number of cars is huge in this forum that uses ASMOIL

diaqueen is over 50$ to get, we give ours away for 10 bucks and you still get a pure synthetic.

but hey i do see your points and i fully agree.

 

Alright so I wanted to give an update, I actually posted in this thread in the first two pages a couple of months ago and I opted to the 75W-140 fluids. The car ran flawlessly and shifted like butter, I cant remember If I went to the track or not, but I know I beat the tranny and launched it and it was perfect.

I had to drain my fluids about a month back because I had to fix my T-case(bolt lost its grip) and I didn't have a way of getting Amsoils so I bought some Valvoline 75W-90 from Autozone and after a week or so my drivetrain started making a weird noise. It might not be the fluid but it started happening right after I switched fluids(Maybe from the change in weight).

So I just pm'd Andy and I got some 20W-50 fully synthetic for my new built motor and 75W-140s for all my drivetrain parts(Tranny, T-case, Rear Diff) and im hoping that little noise goes away.

 

I will have to see what real world testing does at IFO this weekend with your car aka...

 

I havent even dropped off the car for the engine build lol my dump and turbo is still on its way from ER....Im so upset I missed IFO

Are you going?

 

Yeah but won't be running... still working the kinks out of the new set up, I keep having stuff die on me... fuel pump, boost gauge etc... it is getting annoying
