Vehicle Tips

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

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.)

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.

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.

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.

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

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.

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

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.

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

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

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.

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.

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.

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

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

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

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

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

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

What Our Customers Are Saying

I have been using Mid Coast Auto for years. I have never had an issue, they are the only ones who touch my vehicles. Jon and staff are always helpful and always take time to answer questions. The secretary is always friendly and has little talks (if you want) while waiting to make the time pass faster. Mechanics are top notch, there are a ton of people I have referred here. This is the only shop I would recommend.
Have taken my 2003 pontiac here several times. Reliable service from honest people for good prices. They always do what they can to squeeze you into a tight schedule and always communicate with you and keep you posted while your car is getting its work done.
Great guys. Quality work at a competitive price.
Extremely knowledgeable and flexible staff and leadership to provide great service both with customers (like myself) and the vehicle. Personally, I have taken my vehicle here over the past year and will continue to do so as they have given me multiple price point options for fixes and have been flexible with the vehicle repairs and maintenance. Would rate higher than 5/5.
These guys really did a fabulous job in diagnosing the problems with my car. The prices were right as well. They have a lifetime client in me. Highly recommended without reservation.
Great mechanic and friendly and trustworthy. Also Jon explains everything and is very helpful. Take your vehicle to them for sure.
We have a 1999 Toyota RAV4, but you'd never know it was almost drinking age thanks to the team at Midcoast Auto. You've taken such amazing care of our car the past few years, it's never run better! Your prices are super fair, your suggestions are always spot on, and you are nice to my husband. We just made it 1800+ miles to my new job in Nova Scotia, but you'll hear from us when we visit family later this year-I can't imagine we'll find a better mechanic! Thank you :)
I absolutely love this place! We mostly work with Johnny. He is amazing and explains everything so simple. Ive recommended him to many people after he was recommended to me. And the price is always good. I mean for what it is having to fix a vehicle. I am only curious though if they will do work if you have your own parts. Such as my brake pads that have sat under my front seat for a year now waiting to be done. But I love place will never go anywhere else!
They repaired my car in about 40 minutes. Great shop! Everyone is friendly and helpful. Acceptable prices!
Best experience I've had with a shop! After picking up a new set of wheels tires, I was was worried I'd have trouble finding a local shop that would be able to mount them without damaging, considering I've had terrible luck in the past. Thankfully a friend referred me to Midcoast and assured me I was in good hands. Not only did they do an awesome job getting everything mounted (with absolutely no damage), but everyone I interacted with was super friendly, professional, and answered all of my questions. I'll definitely be heading back to Midcoast in the future!
