high mileage vs synthetic oil

[Gussie2000]

I'm still using Castrol Syntec, but the 0w30 'europeon formula' since it's supposed to be a 'group 4' synthetic. Used 10w30 syntec up til a couple years ago. Since i change my oil so often (try to stay close to 2500 miles each time) I suppose it doesn't really matter. Have only used the Mobil 1 filter too. The Mobil M-105 filter fits the VX and is a little longer than the one originally spec'd for it, the M-104. As expensive as oil can be, it's still cheap in mho. Scott

I started using that same viscosity oil,the horse gets warmer a bit faster so it will be my spring/summer oil whist fall/winter would be 0W-20 also by mobil 1

Ok I just got a VX last month and I really love it but I bought it with very high mileage and it needs a bit of work- I know that the previous owner just used regular oil... I am wondering if it is worth it to switch to synthetic at this point. I am ask because I heard that unless a vehicle owner used synth from the start, then the bennifits of using the synthetic oil wont be attainable.

What do you guys think?

p.s. I just hit 140k and I would like it to go another 140k

Hi Aaronk.

You definately should go do that;Mobil 1 is the way to go. 5w-30 for starters.
Another thing you can have done is adding a bottle of sea foam when you are about to have a the last oil change before switching,which will help remove a lot of gunk within the engine.After that oil change the mobil 1 high mileage formula helps sealing gaskets & seals.If more info about the sea foam is needed use the "Search" button & type the word "sea foam"

We have meet on the 25th this month in rockaway,northern NJ.

Hope you wanna join us.If you do go to the tri-state area & PA meet thread & drop your sign there,all the info you need is there.

Again,welcome to hood

if you are going to switch to synthetic i would say go for it.. the synthetic oil is going to release a lot of crud from inside your engine though, so i would recommend doing an oil change after 1000 miles the first time you switch, after that just regular intervals


i actually did find mobil1 full synthetic high mileage at advanced auto, so thats going in today.. best of both worlds
