Yes unleaded is no problem. I sometimes think of taking super premium (the expensive one) to see if the GSI likes it, but so far I haven't tried.
I had a 12 valve GSi for 20k miles and spent quite a lot on it.
Exhausts are expensive and I had a cooling fan (viscous) replaced and offside front wheel bearing (£100 - you have to change the hub assembly]).
I also had rust problems - make sure the chassis number corresponds to the date of registration as near as possible.
It is a great driver and handles very well; much tighter than the 2.0 CDXi I have now.
The trip is about 8% optimistic on fuel. If you stoke the throttle and allow the engine to warm up from cold at low throttle openings you should get 21-23 around town and 26-28 on a decent run.
I would like a 24v GSi but am concerned about the twin cats; they are £200 each and rising.
Also it takes Z rated tyres which are £100 each! If you fit V rated as on a 12 valve car and have a serious accident your insurance could be invalidated.
All the best everybody,
Purchased a 3.0 GSI (12v) auto about 3 months ago. Very happy with the car in general, and despite having completed over 134,000 miles, it runs extremely well averaging 24mpg around town, and 33mpg on longer trips (from the on-board computer).
Am however getting white smoke from the exhaust occasionally, although not using water and not getting variations in oil levels - any advice?
I own a 90 GSi 24v. The car has done 218k now, and although I have a second engine, they will keep performance and live to 300k if serviced regularly.
The only main concern of the 24v (both Senator, and GSi) is the timing chains. They are known to snap from anywhere up from 70k. The main reasons are because the chains aren't strong enough, and the chain tensioner is crap.
There is a club called the Autobahnstormers (http://www.autobahnstormers.org/) which is for Vauxhalls with the straight 6 engines. They know more than Vauxhall about these cars, and it's well worth joining. They can even tell you how to cure known faults, and sort out the timing chain problem!
Hope this helps.
Hello, I'm Matthew. I've just bought a Vauxhall Carlton GSi 3000 12v. It runs, fine but the oil pressure is at 2 bars. It's done 20000k. Can anyone help with my question please, it's not running hot, it runs fine.
I have a Vauxhall Carlton GSi 24v auto. It runs great, but does anyone know how to test the dual ram? The butterfly does move at 4000 revs, does that mean it works? Please, anyone get back, many thanks...
Is there anyway to fiddle the dual ram manifold on a 3.0 24v so it's open all the time???
