No matter what you drive, compression is important. On fleet and commercial diesel engines, it’s essential. At The Brake Shop in Mesa, AZ, we have the knowledge and ability you need to keep your fleet on the road and running strong.

Compression is the most important aspect of how well a diesel engine runs. Since diesels don’t have spark plugs, combustion is a result of compression and heat alone. When your compression takes a dive, a multitude of issues begins to arise. Most importantly, your engine simply won’t have the power it needs to get the job done.

In addition, it may take forever to warm up, and in the meantime, excessive amounts of carbon buildup begin to occur, creating hotspots in your cylinders, clogging injectors, and mucking up your valves. What this translates too is a lot more repair in the near future, poor fuel mileage, and a truck that’s an all-around pain to deal with.

Have your compression tested regularly, and deal with compression issues as soon as they arise. Bad compression can be caused by worn out rings, dirty valves, a failing head gasket, and a variety of other issues, none of which should be ignored or neglected.
