I recently bought a GMC Terrain, and it is already three months old. I've read in the manual that I should change my oil at this time to maintain engine performance. I also found in the manual that I should use synthetic blend oil of the brand it recommends, but I cannot find it in any car shop. What should I do?
When changing your vehicle's oil, the most important thing to consider is if it meets the recommended viscosity of the oil as per the manual. There is a manufacturer's specification there, and you should be able to meet that to ensure that your vehicle's performance will not get compromised. You can choose any brand of oil as long as the viscosity is the same as the recommendation of the manufacturer. When it comes to synthetic blend oil, you may continue to use it if you've used it once. It is a combination of conventional oil and fully synthesized oil. Any brand is okay, as long as the mix is the same as the one recommended in the vehicle's manual.
I'm using synthetic blend oil, and I didn't have any problems when it comes to handling my vehicle. I would like to continue using this type of oil. However, I don't know how often I should change it. The technician told me to replace it every 3,000 miles, but my friends say that is too often. Whom should I believe?
There is no specific interval for changing your oil, and it doesn't matter if it is synthetic or not. It always depends on your type of driving. If you are driving within the city using synthetic oil, then you should be able to go at least 7,000 miles between oil changes. It also doesn't matter if you conduct regular and frequent oil changes, what matters the most is that your vehicle is in good condition. However, if your vehicle is almost always prone to rough idling or sitting in traffic for a few hours, then you might want to check your vehicle's oil level regularly.
The driver's power seat of my vehicle has broken twice in less than seven months. It has been costing us a lot of money. Why is this happening?
This is an unusual problem because the power seats are meant to last for a long time. You should take extra care when you are using your seats. Inspect the yellow wire under the seat for signs of damage or corrosion. Have it replaced immediately if you find any rust to ensure that it will not give in again. You may also bring your vehicle to another technician to check on your vehicle and give you another diagnosis. Usually the breakage of the seats is caused by premature wear due to carelessness when sitting down or adding too much weight on the seat. If your vehicle is already aged, you may want to consider giving it a complete overhaul, which includes replacing all the seats at once.
