Yes, you can with no problem. Virtualy all oils, synthetic & conventional, are interchangeable.
i have a 96 manual and i use full synthetic on mine but you dont have to use full synthetic..if you dont know what is in it right now then i would go for a 50/50 oil(half synthetic and half regular) because you can always go back from there to either regular oil or full synthetic...but once you go full synthetic you can not go back to regular or you will mess up your motor...and you are supposed to use 4 quarts
If you have kept regular oil changes, no prep is required. Just go and put the synthetic oil in.
Why would you want to go back to a non-synthetic oil. Synthetic oil's are far superior to non-synthetic oil.Hope This Helps.AnswerNo, todays oils are compatible and it won't hunt anything changing back and forth
Not at all, you can go from full synthetic back to reg. oil then to semi, then full with no problems unless the vehicle has synthetic only specified for it (eg: some newer VWs)
Go straight to synthetic. There's no need to "wean" it off regular oil.
I would recommend 5w30 and use fully synthetic so it will improve your vehicles life time but remember if you switch to synthetic you cant go back to regular oil it will cause problems but that's the best you can do for your mustang.
you should never mix regular oil with synthetic. it will harm your engine over time. i would go get everything flushed out then add either one or the other.
From my experience I know that there is not much difference. There are exceptions though. If you go on track, tow or drive in really hot or cold weather. Synthetic is your choice. For regular user synthetic oil is beneficial because you do not have to change it as often. Claims that your engine will last longer are not supported (true if you use good quality regular oil).
yes it is fine but of course synthetic is the best to use if you can. Double check your oil requirements with your owner's manual. If it states that normal oil is okay, then go ahead. If your owner's manual dictates Synthetics, then DO NOT switch.
yes you can synthetic oil can go in any engine
If your car originally had full synthetic, then you should go with that. But if it came with regular/conventional oil then it wouldn't be smart to switch unless you have it flushed out because it can cause carbon build-up inside, which will make the motor run harder and heat up more.
