Vehicle Tips

According to recent studies, 5 percent of all motor vehicle fatalities are clearly caused by automobile maintenance neglect.
Vehicle Tips

The cooling system should be completely flushed and refilled about every 24 months. The level, condition, and concentration of coolant should be checked. (A 50/50 mix of anti-freeze and water is usually recommended.)
Vehicle Tips

Never remove the radiator cap until the engine has thoroughly cooled. The tightness and condition of drive belts, clamps and hoses should be checked by a pro.
Vehicle Tips

Change your oil and oil filter as specified in your manual, or more often (every 3,000 miles) if you make frequent short jaunts, extended trips with lots of luggage or tow a trailer.
Vehicle Tips

Replace other filters (air, fuel, PCV, etc.) as recommended, or more often in dusty conditions. Get engine drivability problems (hard stops, rough idling, stalling, diminished power, etc.) corrected at a good shop.
Vehicle Tips

A dirty windshield causes eye fatigue and can pose a safety hazard. Replace worn blades and get plenty of windshield washer solvent.
Vehicle Tips

Have your tires rotated about every 5,000 miles. Check tire pressures once a month; let the tires cool down first. Don't forget your spare and be sure your jack is in good condition.
Vehicle Tips

Check your owner's manual to find out what fuel octane rating your car's engine needs then buy it.
Vehicle Tips

Keep your tires inflated to the proper levels. Under-inflated tires make it harder for your car to move down the road, which means your engine uses more fuel to maintain speed.
Vehicle Tips

Lighten the load. Heavier vehicles use more fuel, so clean out unnecessary weight in the passenger compartment or trunk before you hit the road.
Vehicle Tips

Use the A/C sparingly. The air conditioner puts extra load on the engine forcing more fuel to be used.
Vehicle Tips

Keep your windows closed. Wide-open windows, especially at highway speeds, increase aerodynamic drag and the result is up to a 10% decrease in fuel economy.
Vehicle Tips

Avoid long idling. If you anticipate being stopped for more than one minute, shut off the car. Contrary to popular belief, restarting the car uses less fuel than letting it idle.
Vehicle Tips

Stay within posted speed limits. The faster you drive, the more fuel you use. For example, driving at 65 miles per hour (mph) rather than 55 mph, increases fuel consumption by 20 percent.
Vehicle Tips

Use cruise control. Using cruise control on highway trips can help you maintain a constant speed and, in most cases, reduce your fuel consumption.
Vehicle Tips

Keep your engine tuned. A fouled spark plug or plugged/restricted fuel injector can reduce fuel efficiency as much as 30 percent.
Vehicle Tips

Inspect the engine's belts regularly. Look for cracks or missing sections or segments. Worn belts will affect the engine performance.
Vehicle Tips

Have the fuel filter changed every 10,000 miles to prevent rust, dirt and other impurities from entering the fuel system.
Vehicle Tips

Change the transmission fluid and filter every 15,000 to 18,000 miles. This will protect the precision-crafted components of the transmission/transaxle.
Vehicle Tips

Inspect the suspension system regularly. This will extend the life of the vehicle's tires.

100% Best customer service and work I've had done in my 23 years of having cars/trucks. Helped me out in a big bind! Honest and caring.

Want to thank Rob and family and to let others know if you need anything done on your diesel truck make sure you get a hold of Precision Automotive and Diesel. I'm very happy with the results on both my trucks. We had one bullet-proofed and the other had other work done on it and very very happy. Make sure to come here if you want job done right.

Bob K.
If you want the best for your diesel repairs, there is no one else that comes close. Very professional people, very knowledgeable, clean, neat & every job is done on time. I refuse to let anyone else work on my vehicle because the repair is done right at precision Price is great and very honest.

Bill S.
Hidden gem if you own a diesel truck.

Julia S.
I have gone to Precision on multiple occasions and would go back in a heartbeat. I have a 2006 F250 6.0. I bought the truck used in 2014 with 90k on it. They did a full diagnostic and recommended I "bulletproof" my truck in addition to doing the head studs that are a common fail on these trucks. I did my research and I couldn't beat their price anywhere else. I have driven over 200 miles to take my truck to Precision to get repairs done. They are friendly, prompt, fair and very military friendly. I highly recommend them for your diesel needs.
