Right now I'm using regular dino oil 5w-20 and change the oil about every 4,500 miles or so. With this synthetic oil, how often should I change the oil? What about the oil filter? Wouldn't it be too dirty for that long interval? Thanks for your advice.
Quick question, can I still go back to conventional oil after I used synthetics? my main concern is once I use synthetics (because its cheap now) and can't find any deals later on that I am stuck on using synthetics (more expensive), if that makes any sense.
These quotes are from Valvoline's website:
Can you go longer between oil changes if you use a synthetic blend or full synthetic motor oil?
Synthetic or synthetic blended oils are not intended to extend oil change intervals. These oils are recommended for use in harder working engines and to assist with gas mileage, not to extend service intervals beyond what the manufacturer recommends.
Is it ok to switch back and forth between regular and synthetic motor oil? I heard this causes leaks? Is this true?
Switching between synthetic and conventional oil does not cause problems. Because the oils are compatible, you can switch back and forth as often as you like.
Can you mix different types of motor oil? For example, synthetic and synthetic blend or regular and synthetic? Is this going to cause problems?
Mixing synthetic and conventional oils will not cause any problems. The oils are compatible with each other.
