Subaru Forester 2015: Petrol or diesel?

Answered by CarsGuide 7 Aug 2015

The salesman is right you really do need to run them over long distances to get the most out of them, and they can be noisy, although modern diesels are less so than old ones. You really need to do the maths on the running and servicing costs of the diesel versus the petrol to see which is best suited to your use. Diesels generally cost more to service, and they are prone to blocking of the diesel particulate filter if not used in a way that allows the automatic regeneration of the filter to happen. I would buy the petrol engine.

Supplying own oil at service?

Answered by CarsGuide 27 Mar 2015

The dealer could refuse to do it. He’s got the oil on hand and he wants to make a dollar out of supplying it, that’s how he makes his living. If he doesn’t want to do it, then that’s his prerogative. Yours is to take it somewhere else, or change the oil yourself.

Subaru Forester 2004: XT hesitation issue

Answered by CarsGuide 17 Jan 2014

Remapping the ECU might fix it, but it's not really addressing the problem. It's most likely that it's running lean for some reason. Cleaning the throttle body is a good thing to start with, checking fuel filters can work, and checking the fuel injectors would be a good move.

Subaru Forester 2008: Engine issues after service

Answered by CarsGuide 12 Apr 2013

It might or it might go back to what the mechanic did or didn't do at the service, but there's no way to tell, so you're stuck with getting it fixed. Find a Subaru specialist and take it there if you have lost confidence in your mechanic.

Subaru Forester 2012: Excessive oil consumption

Answered by CarsGuide 26 Oct 2012

The oil consumption is a result of the engine design, being horizontally opposed, and it's not limited to Subaru. Oil accumulates in the rings when it's sitting and you'll sometimes see a puff of smoke from the tailpipe on start-up. It's not something to be concerned about if you check the oil on a regular basis, as you should do on all cars. Use the Subaru recommended oil when topping it up. You'll find that in the owner's manual.

Subaru Forester 2010: Should I use E10?

Answered by CarsGuide 28 Sep 2010

The biofuels people tell us to expect an increase in fuel usage of about three per cent, but that’s offset by the cheaper price of E10. Run a check on your car to actually measure the difference in consumption. Run it on E10 for a couple of tank fulls and then revert to regular unleaded, again for a couple of tank fulls. That will tell you exactly what your car is doing and if it’s worthwhile using E10. We have had a couple of other reports from owners saying their cars are using a lot more E10 than they were unleaded, but the biofuels people and the carmaker involved reckoned there was something wrong with their cars. Running a higher octane fuel will generally improve fuel economy and performance, but it costs more, so you have to balance the extra costs against the benefits to determine if that’s the best way to go.

Is it safe to use E10 in cars built after 2007?

Answered by CarsGuide 9 Sep 2010

Subaru's advice is correct and they confirmed it for us. The problems mentioned by the service manager are ones that might be experienced by owners of old cars, particularly those running carburetors. We also approached the Biofuels Association and they too confirmed that you could use E10 without a problem.
