You might know something about engine compression, but in case you don’t, here’s the crash course.

Your engine relies on compression during operation to pressurize the fuel and air mixture so that it detonates properly and creates power to push the pistons. If your piston rings get worn, they allow this gas and air mixture to escape and your pistons can’t create the right amount of compression. Car engine compression problems can be hard to detect at first but can cause big problems if left to get worse. And for you enthusiasts out there, compression = power. Read More

Your Summer Car Maintenance Schedule

It’s always important to follow the maintenance schedule outlined by your vehicle’s manufacturer – you can typically find that in your owner’s manual. The manufacturer knows what it takes to keep your vehicle running smoothly. Before the hot summer months hit, there are a few additional maintenance items you should consider looking at. A little bit of planning can help you avoid surprises with your car as you head out on vacation and enjoy the warm weather of summer. Trust us, we get a lot of calls from customers about how to handle the summer heat – from both maintenance and performance aspects. Read More

Winter is hanging on for much of the US. Be sure to protect your vehicle from excess wear and friction caused by long periods of idling.

Contrary to conventional wisdom, idling does surprisingly little to warm the engines of today’s gasoline-powered vehicles. Modern engines are engineered so they’ll actually warm up faster if they are driven, not left to idle for long periods of time. Until the engine warms up sufficiently, the onboard computer system is putting extra gas into the combustion chamber. And all that gas is an outstanding solvent that can wash lubricating oil off the walls, causing significant extra wear and friction on components like piston rings and cylinder liners. This engine warming negative effect can be fought off with engine treatment products like our Rislone Engine Treatment, but more on that later.

Diesel engines are often chosen for their excellent low-end power (high torque output) and long-term durability. One of the major differences between diesel and gasoline engines is how the fuel is delivered. Diesel fuel is injected through high-pressure rails directly into the combustion chamber of each cylinder. This is called direct injection and is monitored very closely to ensure the precise ratio of diesel fuel and air is injected for optimal combustion and maximum power. Read More
