Q. My 2010 Toyota Camry has 225,000 miles on it. It recently started using oil but there is no leak or smoke coming from it. What could be the problem? Is it the engine?
A. When an engine uses oil it either drips/leaks or burns as part of the combustion process. More than likely the engine is burning oil either during hard acceleration or deceleration. In both cases, you would not see this unless you were following the car. Considering the age and mileage of the car, the best and most economical choice is to add oil as needed.
Q. Could you give your safest advice as to when to change the oil and filter in my 2019 Impreza. Currently, we are changing the oil every 3,00o miles, but feel maybe could go a bit longer since this is the first full synthetic oil car I have owned since new. I don’t mind changing it every 3,000 miles, which is way cheaper than having an engine issue repaired. I just wanted to get thoughts since I get different answers from many sources.
A. Whenever in doubt, go to the manufacturer, which in the case of your car recommends oil changes every 6,000 miles. Now, of course, with these longer oil changes, it is critical to check the oil and other vital fluid between services.
Q. My car coolant and transmission fluid started mixing causing my transmission to fill up with a yogurt-like substance. I believe the head gaskets are blown out. What is the best solution for this?
A. If it were a head gasket there would be coolant in the oil and oil in the radiator. In the case of your car, there is oil in the coolant and coolant in the transmission fluid, which indicates the transmission oil cooler has failed. The transmission cooler is part of the radiator. Depending on how long the fluids have been mixed together the transmission may need overhaul and
the cooling system completely flushed, as well replacement of the hoses and thermostat.
Q. I have a 2020 Kia Soul I bought new last year (2020). Aside from the recall on them (I have the 2.0L motor), I have a question about the auto-stop. If I’m driving in normal to somewhat heavy traffic, is it OK for the engine to stop and start a lot in stop-and-go traffic? I usually hit the bypass switch in heavy traffic, and then leave it on in normal traffic. My wife (who all of a sudden is a master mechanic) says to just leave it alone. What is your recommendation?
A. Depending on how these system work, some use belt driven systems to restart the engine, hybrids start with the electric motor and others like your Kia just use the starter. Although the battery and starter are fairly robust, constant restarting does add extra wear and tear. In heavy stop-and-go traffic, I would bypass the system as well. My thoughts are what little fuel savings does not off set the extra wear on the starter components. Feel free to take my advice, but then again, I don’t have to live with your wife. Maybe let the system work as design when you are together and bypass the system when you are alone.
Q. Hi, I have a Chevy Colorado ZR2 model and it has 80,000 miles on it. When it hit 56,000 miles it started to have a shudder to it. Now it has become more common. It does it when you accelerate and cruise but soon as you let off the throttle and push the throttle in it will quit. I have changed the fuel pump, mass air flow sensor and spark plugs. A friend of mine told me I needed to get my transmission flushed and that was my problem. Do you think that is what it could be, or do you think something else?
A. From your description it sounds like the transmission fluid is breaking down, causing a shudder in the torque convertor. I would change the transmission fluid and filter and add a friction modifier to the fluid. This has certainly worked in the past on this model.
Q. I have 2019 Toyota Tacoma and it uses synthetic oil. I would like to switch to regular motor oil, something like Formula Shell 5w-20. I always change regular motor oil every 3,000 miles including filter. What would you recommend?
A. There are two issues, Toyota recommends 0W-20 oil and API SN “Resource-Conserving” or ILSAC multigrade engine oil. Based on this recommendation I would use synthetic oil at a 0W-20 weight and change it every 10,000 miles or once a year. Of course, you need to check all the fluids periodically.
Q. I Just bought a 2021 Honda HR-V and can’t find a comprehensive repair and maintenance manual. Do you have any suggestions? I’d like to get a hard copy preferably but would take a download as well. Not looking for an online subscription but a onetime purchase.
A. Even the dealer technicians no longer have paper repair manuals and go online to Honda’s technician site. As good as the third-party electronic databases (AllData DIY is one) are it takes year or so to get up to date on the newest vehicle. With the passage of the Right to Repair laws you can have paid access to Honda repair information, but it is thousands of pages and would make downloading it next to impossible.
Reader Comment: Art Greenberg a moderator at www.fordfusionforum.com wanted to point out that the 1.5-liter engine in the Ford Fusion does have a TSB for a coolant leak, and the repair is the replacement of the engine block. Unfortunately, Ford is only covering this repair under warranty at this time.
