No, you can mix them together if you so wish. But know that you cannot extend the oil change interval if you do not use 100% synthetic and should change the oil/filter every 5,000 miles.
its the same process as changing synthetic oil, except you use regular oil.
Yes but once you do there is no turning back and no mixing regular motor oil ever again with the synthetic oil....only straight synthetic....or use semi synthetic....now that can be mixed with regular motor oil in a pinch.
YES! "Regular" oil is what is mixed with synthetic to make semi-synthetic. Try to use the same brand. I've heard it's not good to mix the different additives that different companies use.
use it, it is ok to mix
If it has the right rating, nothing.
You would use the same oil filter for both synthetic an d regular oil in your jeep.
You can use either conventional or synthetic, your choice.
i use 10w30 synthetic oil in mine, or u can just use 10w30 regular oil but the synthetic lubricates better and i notice that the engine makes less noise when i use synthetic
yes, if the car manufacturer dictates that regular oil is acceptable. If your car requires synthetic oil as dictated by your owner's manual, then DO NOT use regular oil. May void warranties if your car is still covered.
Regular oil is recommended by Jeep. Edit: Correct, Jeep does not make a recomendation to use synthetic oil. However synthetic oil will not hurt the engine at all. The recommended weight is 5w30.
if it's a turbo engine you should only use synthetic oil only!! if it's a non-turbo engine a conven. oil will do.
3000 miles if using regular oil, 6000 if using synthetic. I use synthetic for my RSX-S, but regular would do for a base model.
