high mileage vs synthetic oil

[circmand]

im now over 80k miles.. my vx is growing up so fast!

heres my question.. my last 40k have been run with mobil1 full synthetic almost exclusively.. (5w30 and 10w30 depending on season/availability) but now im wondering if it would be better to switch to high mileage formulas or to just stick with regular synthetic.. i havent seen a high mileage specific synthetic.. anyone make one of them?

and i always run a mobil1 filter (except this last change, i got a K&N oil filter at a great price)

Makes a synthetic for high mileage

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

all done purring like a kitten... i forgot how easy doing an oil change on the VX is

Good advice Gussie2000 and etslsport - yeah, I am definitely going to switch to the synth - thanks so much for the quick responses and good advice ! Will look up the sea foam and do a quick change after 1000 miles.

Also Gussie - I am going to make it to Northern NJ meet up - I just changed out my shocks to Bilsteins and I am no longer afraid to drive through the wreck of the a highway running through the Bronx !
