Anyone try this stuff instead of the redline type R?

After many days of web searching I keep coming across a lot of people that are only specifically recommending this fluid having switched from a redline fluid before. Interested to get some of your guys thoughts. IHC have you ever heard much about it or tried it?

 

Seems as many put anything but the factory fluid in the TL, even if it's not recommended, so give it a try. At least it states it meets or exceeds Z1 specs.

 

I've never used it and I don't know anyone who has. I can only guess since it's a universal fluid it's close to a DexIII fluid. I'm sure either viscosity would work. The thick version isn't that thick and the thin version is t that thin. They don't offer a whole lot of information on then ATF but it has a high viscosity index which is good but it indicates the use of VIIs.

I looked at the oils. The street oils have a fairly low HTHS and a high volatility. It would be a safe assumption that they rely heavily on VIIs. The racing oils have very little info.

Maybe they have a badass additive package but the MPZ technology they refer to repeatedly looks like regular zinc, phosphorus, and moly that you can get in other oils. They say the base oil is a blend of grpV and IV which is fine but there are other oils available cheaper that are almost entirely grp V. I guess I don't understand the very high price. I wish they would give more info so we could understand what justifies the price.

I surely wouldn't be afraid to try it in the TL, especially if you live in a cooler part of the country. I would be interested in your results. I think this fluid compares closer to DexIII than the Type F racing fluids.

 

I don't see any compelling reason for paying $18 for Torco (which I used a lot of 2 stroke oil from that brand and has been around for 40+ years) .vs. Redline that's around $11 online. I would stick with Redline or DW1 personally. If Torco was $7, I might consider trying it out for one fill possibly but not at $18.

 

IHC do you know anything about using "Tractor hydraulic fluids" I read that a lot of these racing ATFs are just tractor hydraulic fluids.

 

Richie. That was the other automatic fluid I came across. MANY guys compared it to redline ATF without the price. But many people who reported slow shifts and slipping of clutches said that running that john deere fluid I posted on another thread solved the problem. Firmed up shifts or made it so they didn't have clutch slippage anymore. That is another fluid I would like to give a shot to. Reason I keep asking IHC to try it is because he is the only one I know that has tried several fluids in his car and so for him to try it we get a better idea of how it compares to other fluids.

 

There are two I've seen, hydraulic fluid and hydrostatic fluid. The hydrostatic has some FM. The hydraulic does not. All of the people I know that run it do so to tighten up the torque converter which is something we don't want to do.

 

You are correct. Some were using it as a performance filter, but many said and used it to tighten up a torque converter.

 

I just went with a D6 (DexVI) and Lightweight Racing fluid (4cSt) in mine and coming from a 10cSt racing fluid, the converter definitely has a little more slip. For the TL I consider this a good thing since it feels a little more alive off the start. Instead of the rpms coming up and hitting a wall, I can be accelerating and give it more throttle and the rpms come up more (no downshift). It's a subtle difference but it's enough to make the car feel a little more lively, almost like it lost a few lbs.

I could see using a thicker fluid if you had a loose converter and were trying to fine tune the stall speed a little but after my experience, the TL seems to like a thinner fluid. It improved in lots of areas, just about every area but full throttle upshifts.
