No modern car uses 10w40 oil. Use what the owner's manual recommends. There are special blends for High Mileage vehicles, but stick with the correct weight.
SAE 10W30 unless it is high mileage which in that case use SAE 10W40.
I would use 10w30 and for high mileage 10w40 would work best
Mobil 1 10w40 very high performance is the best oil to use unless you have very high mileage in which case use 15w40.
Hyundai recommends SAE 10w40. On a car this old I recommend you use a High Mileage oil.
This is not advisable. You should use 10w 30w in this vehicle. Unless the 10w40 has been advised by the manufacturer.
I would recommend you use SAE 10w40 any major brand high mileage oil.
10w30 any major brand of detergent oil unless the engine is high mileage and worn, then use 10w40.
I recommend a high mileage oil such as Pennzoil High Mileage in the weight the manufacture of the vehicle recommends.
No, you can and should use high mileage oil if the vehicle has over 100,000 on the ODO.
It depends on what mileage your car has. Personally, i use 10w40 and my car has 145k on it.
yes, but will decrease fuel mileage a little, may not be noticeable, and will help with noise and leaks too...
Use a High Mileage oil in the exact weight the manufacture of your vehicle recommends.
