Project BMW 318is: A Word About Lubricants

We always use good, quality lubricants in our project cars. For our E30 318is project, we partnered with Red Line Synthetic Oil and used their 10W40 street (as opposed to pure race oil, which does not have the correct additive package for street use) full synthetic motor oil.

In the transmission we used their MTL, which we have always found helps an older transmission shift more smoothly and more easily.

We love MTL and use it on almost all of our project cars. Nothing loosens up an old gear box and make its shift better.

In the differential we used their 75W110 gear oil.

Your author installs the gear oil with a small transfer pump (available at any auto parts store). We have never had a failure when using Red Line Synthetic Oil.​​​​​​

With this lubrication package we feel confident to run any track day or autocross activity.

Red Line makes a full range of fluids for your car, including hi-temp brake fluids that has served us well at both Virginia International Raceway and at the Tail of the Dragon.

I think Redline makes good products. Years ago, I switched our national champion Jetta GLI to Redline MTL in the transmission, and it made a big difference. It definitely improved shift quality by improving the performance of the synchronizers.

I had a friend who ran Redline racing motor oil in his Formula Vee road race car. He told me he only changed the oil once per season, and never had a failure.

I am about to get a 1990 325i that has been sitting for 5 years.  I am planning on flat bedding it to my house and starting on the project.  Do you have any info on where I should start the project. I have been following this 318 project and am open to any guidance you may have,  Thanks Dave

Is that not an orange-tag transmission that specifies ATF? Did you purposefuly choose to use MTL instead of Redline's ATF?
