Quote It is good that your trial did not indicate any harm but I'm not really sure how you would know. But at the same time there's also no actual evidence that the additive does anything beneficial either. A few videos of people claiming stuff, or testimonals on a website are not the same as...

I received two bottles of MotorKote for free with a vehicle, started researching went down several rabbit holes when I should be working, ended up here. I've long been VERY skeptical of ANY oil additive believing based on my own and others VOA, UOA, and other independent controlled scientific...

Hate2work, I have read that spec as well, Mitchell lits is as 4.2q with filter...Yet every 2.5 V6 powered car I've owned (there have been several) take 5q to put the oil at the full mark after running them. Can't explain why :) On this car I run a filter from a '93 Corvette ZR-1, same fitment...

hate2work, total track time was 2h 40m plus a 60mile round trip to the track. How is it a 12.5w? ((20w*4)+(5w*2))/6 = 15? Is there something at work here I don't understand? 'Cause that's entirely possible :p bulwkle, During the hotter months over ~90deg I run straight 20w50 Redline for the...

The car is a 1994 Mazda MX6 with the 2.5L V6. The engine is the original stock engine with 125k miles, only bolt on modifications. It's used primarily as an autocross and track day car. The oil is 4 quarts Redline 20w50 and 2q Redline 5w30 to achieve ~15w40 mix. Oil filter is a Napa Gold P/N...

I have an empty sample tube from Blackstone...I'm tempted to find out what's in it, but I'd much rather save the $22 if somebody already has??

I've got a customer that wants me to put this in their car...anybody have any new info on this additive?? Ryan

Wow Jim, thank you so much. I assumed it was basically a formula containing something similar, and probably more EP additives...Moly in some form I'd assume...to smooth things out. And so far it has. While my tranny is still farked it is a bit nicer to drive. And good to know about the Ford...

I know that the BG synchro shift is good stuff from what people have told me. And our distributior for BG products came into work the other day so I asked him about it...Yikes, $14 a quart...anyway I told him the issue I was having with my 1G PGT with grinding into 2nd when I shift fast at high...

Wow, Yeah, I completely did not see the forum for this (late night), thanks for moving it! And thanks for the links, helps a lot. Though I didn't see Bosch anywhere. I've been using them for some time now and can never seem to find much on them. Seem to be of good constructon upon visual...

So far I haven't blown any trannies on redline. Had it in four different transmissions in three different cars and loved what it did for shifting over standard ATF. Laters Ryan

Just what the title says, either I haven't found them yet or don't know where to look. I'd love to see some comprehensive testing done on the major oil filters out there. I've got some basic knowledge as to which are better than others, but no hard evidence. If none is here, does anybody have a...

Anybody? Laters Ryan

Most GL4 rated and GL4/5 rated fluids have inactive or "mediated" sulfur-phosphorus packages as the basic EP additive. In addition they have rust inhibitors which form films to protect against rust, and metal deactivators to prevent the metals and the EP additives from catalyzing into oxidants...

I'm having a very nice long discussion on the benefit of GL-4 over GL-5 oil. So far through searching on this site I've already learned a LOT. Anyway the topic of our discussion is basically about the safety of GL-4 versus GL-5 and it's sulfur content and how it affects 'yellow' metals...
