Dear Mr. Granquist:
I wanted to send you a letter describing the terrific results I have obtained using Red Line products.
I purchased a 1994 Mitsubishi 3000 GT VR4 in July of 1999. I had always wanted one of these all wheel
drive, 4 wheel steering, and twin turbocharged V6 cars. The one I found had low mileage and was in
excellent condition. I wanted to be sure I was maintaining it with the best products possible. After
doing some research I settled on Red Line as the best choice for fluids.
In September I changed the oil to Red Line 10W30, the transmission and transfer case to a 50/50
blend of Red Line MTL/MT-90, the differential oil to Red Line 75W90 Gear Oil and I added Water
Wetter to the cooling system. At this time I was having other work done on the car (tune-up, filter
changes, etc.) and the mechanics reported that the intake ports were fouled. They recommended I try
Red Line S1-1 Complete Fuel System Cleaner as a first step to clearing up the problem.
Here are my results:
- I had a bottle of Red Line Sl-2 Injector and Valve Detergent so I put this in and ordered a case
of Sl-1. I added the SI-1 at my next fill up. I ran this tank of gas and then took the car back to
the mechanic. The check of the intake ports showed they were completely clean. Everything
else in the fuel and injection system looked great too. l'm glad I bought a case of SI-1 because
now I use it regularly at the maintenance dose. The results here were just great.
- One disconcerting thing about this car when I bought it was the shifting feel. It is often referred
to as "notchy". This is the awkward feeling that you can't smoothly transition from one gear to
another. I also found that downshifting could be difficult, particularly from 4 th to 3 rd . Most
people say that this is just the nature of the all wheel drive, six speed transmission. When the
transmission/transfer case fluid was changed there was a very slight improvement in shifting
ease. After about 1000 miles the improvement became quite noticeable and by 2000 miles
the shifting was virtually perfect, as good as any sports/performance car I have ever owned. I
had a chance to compare shifting ease with my brother in laws brand new BMW, and my car is
now better. He drove the car and said it shifts better than his 1998 Porsche Boxster. I
consider the results phenomenal given that this is an all wheel drive car.
- Since adding Water Wetter I've noticed that the engine temperature reading holds rock steady
regardless of the type of driving I do. Neither stop and go or sustained high speed driving will
result in any change in engine temperature. Once the temperature rises from a cold start to a
stable reading it just stays there. Consider how remarkable this stability is in light of the fact
that this engine supports two turbochargers and even when pushed hard (sustained boost
pressure over extended run intervals) it stays put.
- I can't say that the Red Line engine oil and/or gear oil has done anything obvious for me. At
the same time l'm so pleased with the results from your other products that I feel much better
using Red Line whenever and wherever I can. I'll be changing the power steering fluid to Red
Line at my next planned service.
Please accept my thanks for making great products. Also, please accept my thanks for your
prompt and personal e-mail replies on my questions concerning which products to use, change
intervals and your general advice.
I am very impressed with Red Line products and service. I am definitely a devoted user and vocal
proponent of Red Line. From my point of view no one who owns a performance car should even
think of using anything else.
