I'm trying to find Mobil 1 Delvac 75W90 oil. Has anybody located this stuff recently? I wonder if any US dealers would even ship this stuff. In Canada this is only available in 20 litre pails (5 gallon) at $185. The dealer carries the Porsche stuff at $50/litre!

ps the new Amsoil Severe Gear lube performed worse than the 68000 mile stock stuff. There goes $75.

I ordered them from here before http://www.lufteknic.com/Merchant2/m...ode=lubricants

+1 on lefteknic
Their customer service is freakin' amazing.

I'll try them. I thought the oil was no longer available from them based on another thread.

the SHC version is no longer available... the delvac version is. They say it is only a packaging change.

Thanks. I made an inquiry to see if they will ship to Canada but they require a wire transfer and can only ship via ground. I might as well buy the 20 litre pail. It should be a lifetime supply. Any locals want to split it?

Lufteknic is a few miles from me. Let me know if I can help get what you need.......

A side note on the gear oil:

I have tried just about everything in my 993's manual transmission. (No LSD tranny)

Mobil 1 75W90, too slippery during cold winter days synchros do not speed up fast enough

Redline 75W90 (with friction modifier added already), also too slippery

Swepco 201, pretty much solved the synchro issues

In my 996 I tried a 75W90 fluid from Specialty Formulations call MTL-R, the best tranny fluid I have ever tried. Shifts super smooth cold and warm, after nearly 30k miles the fluid came out almost like brand new, no debris no discoloration. Unfortunately SF went out of business, so the most recent 90k miles service I crossed my fingers and put in Redline 75w90 NS (No friction modifier). Surprisingly and I was super happy with the results, if anything it is better than the SF fluids I had in the car. FWIW, the 996 transaxle is different in construction to the 993 as it is made by Getrag.

Two weeks ago I did a yearly full fluid service in my Ferrari 360, I started with regular Redline 75w90 with FM, it didn't shift well at all when cold. So I tried another formulation recommended by several Ferrari techs. Redline 75W90 NS (no friction modifier) and separately add FM (8 oz) to be exact for the LSD not to bind up. Now my Ferrari shifts perfectly cold and warm with this combination.

I can get Redline from a performance parts store a block from my office. Would you recommend the Mobil 1 Delvac or the Redline NS then (no LSD)? Thanks.

My experience with the Mobil 1 Delvac was also very good for the 993, so it is a toss up. But if it would be easier for you to get the Redline oil, why not give it a try.

I like to use Redline product across the board due to the simple fact that it is a group V synthetic oil. Meaning made from 100% synthetic stock, not the partial stuff Mobil uses and calls it sythetic.

Thank-you. I'll probably give the Redline a shot first.

I bought the same stuff from lufteknic and it didn't work well at all. It was way to slippery for the synchros when hot. I had to go to the dealer to get their stuff that is as close to the factory fill.

matt777

The dealer stuff (Packaged for Porsche) is $50/litre! I wonder who makes it and what is in it?

matt777

Bought some Redline 75W90NS for $50 so we'll see how that stuff works. It looks like the NS does not have much or any of the friction modifier in it for the limited slip while their other gear lube does(??). My plug seal rings just arrived from Pelican along with a Motive bleeder, air and oil filters and a console storage tray and mat. Good timing!
