Now I have moved back to Australia I am looking for someone to service my S1 Elise. I found a specialist British Sportscar Garage who look good, and they only use Red Line Synthetic Oils. I have never heard of these before, but their brochure looks impressive, and their website (www.redline.com) is professional. The headquarters is in Benicia California.
Does any one have any experience with Red Line Sythetics ? Any good ? What is the opinion on this product line before I trust my engine to it ?
Any help / opinions appreciated.

I swore by Redline in my competition car.

I have had good luck with Redline everywhere but my transmission. When I put it in my tranny I got "gear gnash" because it was "too" slippery. I went to a semi synthetic in my tranny and have had MUCH better luck.

Redline makes viscosity adders for such applications....look into them carefully.

I also used their shockproof oil in my rear diff with good results until I went to a KAAZ LSD..now I run KAAZ fluids.

I don't use Redline myself, but their products are highly regarded. The only question is if it's worth the price premium over Mobil1.

As OFM mentioned, some cars can be peculiar about transmission oil. Try to find out from other owners what works best for your car. People have had mixed success with Redline transmission oil in Subarus, too.

Redline tranny fluids as stated are very slippery. I've had a number of discussions with the Redline folks & a friend that is one of their largest distributors. The gear gnashing is because the syncros actually don't get enough friction to fully function. This really shows up on an older car where the syncros are worn.

I use Redline tranny oil in my Hewland w/ straight cut gears. It's fantastic. I'm able to use a lighter weight and still exceed the protection of a heavier weight standard oil.

The stuff I've heard from Redline is use their tranny oils in a newer or new car where the syncros have yet to wear. It will make the them last a lot longer.

I use Redline in the engine, gearbox, and differential of my Seven, I am very happy with it. I use the car for autocross and track primarily, very little street driving.

Thanks guys, you have given me some confidence. Appreciate your feedback.:clap:
Mitch - I thought you should know the price through your Race & Prestige connection !! This was an MG specialist, and I looked at him in desperation because I needed a cam belt change and at least he is familiar with the K series via the F. I am stuck in Perth where I can't find much help with my Elise, but when I move East at the end of this year I hope to have better luck over there !

I use Redline MTL in the gearboxes of my cars (Type 9, VW, Getrag).
I use Redline Diff oil in the se7en with quaife, and a combo of Redline gear oil(reg and Nonslip 75/90 in the M3).
Speeds up the shift when the box likes it.

What's the best oil for LSD (torsen type - not plate clutch type)?

BTW - my theory is that the stock fluid works best for street and Redline MT90 works best for track. I got a lot of grinding and difficult shifts with the stock fluid on the track. That stopped with MT90. For track use I make sure the oil never has metal particles in it since that causes too much friction and makes the shift engagement sticky. I change it every 1000 track miles or 5 track days to keep it clean. I guess I could strain it, but that takes too long.

in my non-lotus I use redline shockproof oils. I use to use MTL however it thinned out way to much during track time so I went with MT-90 for a while which was definantly better but still thinned out. Redline added the shockproof line to their oils & this is definantly the best trans oil I have used.

I would look into it... you can call up redline & ask for their suggestions as well.

I use to change MTL/MT90 before each school.... now I get 2 years out of the oil :)

The shock proof works good in a rover gearbox, and the engine oil seems to work fine for me in the engine.

Depends somewhat on the diff, but I've found Redline Heavy Shockproof to be simply awesome in torsen LSD diffs. I use it in just about all of my cars, though for a combined diff/trans you might want to try the Light Shockproof.

Run MTL in the Loti, and they're quite happy with it.
