just got my car on Friday and was curious if anybody is running synthetic with their Stratus? If so, special brand or type you suggest? upgrade the oil filter too? advantages/downsides of doing this? Thanks in advance...
I also run Royal Purple everytime with a PureOne filter. Just as good a filter as the more expensive ones at half the price. Drop a bottle of Chevron Injector cleaner in your gas tank every other oil change to keep your fuel system clean too.
I run Amsoil also. It has it's own warranty, and a vehicle manufacturer cannot void a warranty unless they supply you with engine oil and you use another brand. Other than that it's free game as they will not test the oil providing you can prove that it was changed within the recommended service schedule. Most ppl change at 3K as that's what specified under the 'severe service' schedule. Under the 'normal schedule' also known as the ideal schedule, it's twice that at 6K drain interval. So running synthetic oil at 6K is allowable. Just make sure that it states somewhere in the owners manual that it can go 6K and you'll be fine.
You can switch back after running synthetic, it's just not the ideal thing to do as you'll have to change out the oil at shorter intervals and if you decide to switch back, an engine flush would probably be a good idea. With that said, along with the longer drain intervals synthetic oil provides it's actually more cost effective per mile to run synthetic oil. Not to mention the fact that it's better for the engine!
I have been running Mobil 1 in my truck since its first oil change, along with a Bosch filter and the Techron Fuel System treatment every 3k-5k miles. I don't drove my truck much and I kind of take the extra mile when I change my oil, meaning I probably change it too much, lol.
I just started putting Mobil 1 in my Stratus. I bought the car used at 66k miles and I have probably put 10k on it so far within a year. So I don't drive much.
But yes, I recommend using a good brand of synthetic oil, along with a good filter.
