Is fully synthetic any good?

[aj1]

I have been told that fully synthetic oil is not worth bothering with unless used from when the car is new. I have a saxo vts any suggestions for the best oil.

Who ever told you that is a bit simple unless he qualified it with 'If it uses a lot of oil'.
And even then mechanically it's worth using Full Synth but maybe not financially.

Ask the Oilman for recs.. www.pistonheads.com/gassing/topic.asp?t=237642&f=23&h=0

Dunno what my car ran on till I bought it, but my oil temp is more stable now using fully synth than it was on a semi. Used to flare up and stay up with any hard driving, but now it takes time to build up and doesn't get as high. I expect when it's hotter it'll stay more stable too, so will protect the engine longer (hence why fully-synth intervals are longer than semi for most cars)

The difference in cost is that small next to fuel and tyres why worry about it? £45 an oil change every 12k or 1yr?

Isn't there a problem with Fake oil mixing with real oil??

No it just becomes 'part synthetic', as long as the oil spec is the same then there shouldnt be any problem.
