ENGINE MAINTENANCE

Diesel engines power a wide range of vehicles and equipment, from trucks and buses to construction machinery and agricultural equipment.

These engines are known for their durability, fuel efficiency and ability to handle hard work and heavy loads. But their resilience and efficiency hinge on good upkeep.
By sticking to a diligent maintenance routine, you can optimize your diesel engine’s performance and significantly prolong its operational lifespan.

SEA FOAM MOTOR TREATMENT

cleans and prevents harmful fuel and oil deposits

Sea Foam Motor Treatment is safe and effective when used in any diesel engine fuel (and crankcase oil!). In fuel it works to clean injectors and add upper engine lubricity. In oil it works to clean and liquefy heavier oil residues and deposits.

HOW TO MAINTAIN YOUR diesel ENGINE

diesel vs gasoline engines

Differences between diesel and traditional gasoline engines are fundamental. While gasoline engines ignite the fuel-air mixture using spark plugs, diesel engines achieve combustion through high compression. This enhances diesel engines’ efficiency and ability to produce higher torque at lower speeds, but also necessitates specific maintenance practices to avoid issues such as overheating, clogged filters and injector problems.

A MONEY SAVER.
“I bought a 1981 Mercedes diesel a few years ago. I suspect it had been sitting for a long time. While driving it over 70 mph the engine started losing power and eventually stalled out. After some consideration I figured that at that speed debris or algae must be blocking the tank filter. I limped but home doing 64 mph. My mechanic recommended removing, draining and cleaning the tank. For whatever reason I decided to give SeaFoam a try. I used two bottles and then took it out on the highway to see if the car would still have problems driving over 70mph. No problems whatsoever. No problems since then either. I became a customer and believer. Thank you SeaFoam.”

Since the late ’50’s it is the BEST thing made for combustion engines!
“I was introduced to Sea Foam in 1959 by an Uncle who was a great mechanic. He swore by it and I started using it on boat motors, lawn mowers, old cars. I still use it today with both gas and diesel engines. I always have several spare cans in the cars, trucks and the motor coach. I am a Sea Foam evangelist just like my uncle was in 1959.”

SOLVED AN ANNOYING ISSUE
“i have a 2007 Silverado 2500HD Diesel that kept sending a trouble code for a dirty/faulty EGR valve. Before I tore the top of the engine off just to clean or replace it I tried a hot soak and tank full of Sea Foam. It cured all the issues and haven’t had the truck shoot the trouble code On over a year. Saved me a bunch of money in parts and labor. Also use it in both my snow blower and ice auger with great results. Love that stuff.”
