John W. Baillargeon from John's Performance Shop in Port Orchard, Washington:

"I would like to pass on a recent experience involving Red Line 20w-60 HD oil.

A customer of mine brought his 1998 Harley Ultra Classic to me directly following a ride he had taken to South-Central Washington. He told me his oil pressure light came on roughly 200 miles into the ride and the bike started making noise. Instead of acknowledging the pressure warning he continued to ride the bike to my shop. I literally heard the engine clatter before I heard his exhaust.

When he got to the shop the engine sounded like a 40's vintage thrashing machine (tappet failure). I inquired how long the oil pressure light had been on and he told me. I told him that he had very probably just bought himself a new engine based on the abuse he'd leveled at his old engine.

I had previously talked him into using Red Line 20w-60 HD because of the success I'd had with it. I disassembled the engine and found that his gear driven oil pump had sheared 2 keys and was totally locked up (I had to use a hammer and punch to remove the shaft/gear assy.) The resident oil that was in the crankcase at the time of the oil pump failure amounted to about 8-10 ounces. The only lubrication the lower end of the engine got was via splash method in that small oil bath.

The tappets had failed however. That was the only component in his engine outside of the piston rings that couldn't have been reused. The pistons were not scored and the cylinder walls had light scuffing consistent with the 40k miles on the engine. Even the valve rocker shafts and bushings were useable. The lower end bearings were in perfect shape. I kept his pistons as a reminder (customer opted for high compression setup).

I think it goes without saying that I was totally surprised and impressed at how well the Red Line had literally saved this customer from ripping the heart out of that engine. Before I went into the engine I would have never believed the outcome. The customer is totally convinced about Red Line and I am more than ever convinced that using Red Line synthetics is an investment in keeping your engine as good as it can be."

Ross Willis from Australia:

"My truck has always had a problem with running hot, especially in the city and being on gas with just the fans ...stuck in traffic on a hot summers day can be a worry. So when my next service was due, I decided to try some Red Line Engine Oil and WaterWetter. I could not believe the difference it made. The first thing I noticed was the engine ran quieter and the engine idle speed had increased, apparently due to less friction. The running temperature of my truck has reduced so much that it takes an extra five minutes to heat up to running temperature in the mornings."

Joe Gaerte from Gaerte Engines:

"Red Line Synthetic Oil is the company that I have chosen to provide all of my sprint car lubricants. I have tried many different lubricants and motor oils from several companies over the 13 years I have raced sprint cars, and seen several tests performed. I choose to use Red Line Oil because of it's superior quality and results."

J. R. Granatelli:

"In my 12 years of Mustang racing and my family's 40 years of USAC, IRL and CART, I have never come across a line of lubricants that does a better job than Red Line Oil. We turn our engines upwards of 11,000 rpm and have never had an engine failure related to oil break down. We enthusiastically endorse all Red Line Oil products."

Tom Morgan from Tom Morgan Racing:

"Your synthetic suspension fluids are absolutely the best! The longer that I use them, the more advantages I find in using them. Fluid change intervals can be 3-4 times longer than with any other suspension fluids and heat fade is essentially nonexistent for motocross racing usage. Thank you for producing products that allow me to provide the best engine and suspension in the motocross industry!"

Mike Moran:

"We use Red Line Oil exclusively and while developing improvements on our clutch program, we warmed up the motor as usual, did a burnout and went to the 60ft. mark. We noticed the engine had been misfiring. The next full pass was completed with the clutch in working order. Our main concern was to modify the clutch and we weren't as focused on engine performance that day. Later we had realized that we lost our oil pump belt and the engine data concluded that we had no oil pressure for those passes. To our amazement there was no bearing damage at all, which is pretty amazing considering the power level was nearly 2,000 hp, which proves that Red Line Oil really holds up! Thanks!"

Mike made drag racing history by being the first street legal car to run over 200 MPH at the 1996 NHRA U.S. Nationals with a record of 6.96ET at 201.2 MPH.

Jim Dunn ----- K&N Filters Funny Car Owner/Engine Builder:

"After half of a century in drag racing, I know to only use the best. That's why I highly recommend Red Line Oil."

Doug Mangrum, Pro 5.0 Mustang, 6.76 @205:

"Since switching to Red Line Oil, we have qualified #1 six times in the 2001 season. We also had three wins and one runner-up. It is the best racing oil on the market, period!"


The amount of money spent on the stuff poured into a car's gas tank is staggering. It's a market worth hundreds of millions of dollars annually. We don't endorse fuel additives as a general solution to undiagnosed drivability problems. However, there are specific cases where a detergent-based fuel additive may solve a moderate case of restricted or leaking injectors. The key phrase is "detergent-based". Some mass marketed injector cleaners are solvent-based. Using solvents is a less expensive way to create cleaners. The problem is, they seldom contain a strong enough solvent to fix an injector because too powerful a solvent can damage other parts of the fuel system. Detergent-based injector cleaners can be very strong and not damage the fuel system. One such cleaner is made by Red Line Synthetic Oil. The point in the injector diagnosis in which to use a cleaner is after the initial steps have failed and before you do an oxygen sensor test. Run two bottles of SI-1 through the engine, mixing one bottle to 15 gallons of gas. Pour-in cleaners work. We know of one case where an '88 Beretta GT was maintained with a bottle of SI-1 every third fill-up. After 88,000 miles, the injectors were pulled and inspected against a new set of AC/Rochester units. The injector tips and the area inside the tip below the director plate were as clean as that on the new injectors.
