It is better to stay with the same brand but if you have to change it for one or two oil changes its ok make sure its the proper viscosity for your vehicle

What type of oil should be used in a 1989 ford bronco

Depends on how many miles it has on it, I prefer High mileage castrol GTX 10/40 Detergent for most v-6 motors or I will use the synthetic oil to get longer life out of it.If it is low mileage then you can use castrol 10/30 or Mobil oil 10/30 or Texaco 10/30 or 10/40 depending on mileage. If it has a lot of miles on it the lower viscosity will cause it to burn or leak oil.

What motor oil can i use for my 1.5L 5E toyota corolla 1996

Hi: I would recommend using 10w-30w GTX Castrol,Its a Good Grae Oil.

If you just bought this car you should try to find out if any Synthetic Oil was Used in it, Cause once thats used you wil want to Stay with Synthetic.

Hopefully you Know or Can find Out. But the GTX Castrol I've used for Years Its a Good Quality Oil.

Burning oil...what oil to use in 1998 olds aurora 140K miles

Many engines begin to drink oil at or around 100K miles. I found that Castrol GTX High Mileage oil will get me to the next oil change (at 5K miles) without having to add a drop, where as before I made the switch I was having to add two quarts just to get there with the generic stuff.
