Most auto part stores will loan enough tools to test what's wrong. Check your fuel pressure, your cylinder compression, and make sure your ignition system doesn't have water damage. If there are any DTCs those would help pinpoint the exact problem also.

It's not just performance that's suffering if you use a fuel less than recommended.. You're doing unseen damage to your head gasket. By the time it's noticeable, it's too late and you've caused an expensive repair that could have been avoided. If your owner's manual says 87 or higher, go with the higher! Subaru is having a huge problem with their head ...

Even if you're ecu changes to help prevent damage to youre engine, you're still causing damage to your head gasket.. This is one of the reasons subaru has had so many head gasket issues.. The manual says 87 or higher recommended... They didn't want Americans to not buy the car if they recommended premium fuel for an awd car.. So if the car says 87 or higher, ...

I think they are worth using but there are some things to keep in mind. First off, if the car is old and the injectors very dirty and clogged, chances are that no liquid additive will get them clean by itself. The Berryman B-12 Chemtool is one of the strongest solvents, so try that, but if that doesn't do it, your probably aren't getting them clean this ...

I agree with Paulster2, it's very probably that you have water trapped in your exhaust. After it runs for a few minutes, is there any steam coming out of the tailpipe? A little steam is normal after first start up but after the engine warms up it should stop. If you have a never ending source of steam you can take apart the exhaust system and dump it out ...

I finally took the car to a shop. It turns out that the problem was the charcoal canister, which needed to be replaced.

To my knowledge the reserve setting is for reserving that last bit of gas. If the bike starts to sputter, you're probably low on fuel,you can then switch reserve and have maybe another 50 miles of fuel left. I always set the valve to off if it won't be ridden within a days time. But the carb flooding is also a damn good reason to use it. Parking for a while ...

Thanks for the replies all. I found it was actually the pump. Whilst it was working the bearings were shot so it wasnt working well. Replaced and all good.

I eventually found the issue: the fuel lifter pump was faulty. For those that dont know, the Mk1 has 2 fuel pumps - the main one underneath the car and a 2nd 'lifter' pump that sits inside the fuel tank. This 2nd pump's bearing were gone. The primary pump had enough power to run the car but I guess the g-force under braking overrided the fuel pressure ...

Mixing 95 octane gasoline with 92 is perfectly fine. In fact, this is what many gas stations do in order to offer their mid-grade product. For example, many gas stations in the United States offer 87, 89, and 91 octane gasoline. The 89 octane gasoline is a 50-50 mix of 87 and 91 octane gasoline. Mixing grades of gasoline will not harm your engine as long as ...

To answer your question directly, adding the 95 to the 92 in your tank will not cause any real problems, in the short term. Once you have used the tank full you can carry on filling up with the recommended 95. Modern engine ECU programming will adjust the timing of your engine, knock sensors, to minimise or prevent engine 'pinking' caused by the lower octane ...

As it happens with many such questions, the answer is "it depends". Diesel engines are more expensive. In long term, diesel engine car is cost-efficient (taking into account purchase price and fuel costs) when you are making greater mileage per year. It should be easy to calculate savings on fuel vs higher purchase price of diesel-equipped vehicle. ...

also Diesel engines have a longer stroke than ordinary petrol engines. which means pistons travel a longer distance that it does in petrol engines. And turbo/super/ram air intake systems have completely different timings than naturally aspirated petrol engines.

Some diesel engines will have problems, others will not. It all depends on how the injection system works on the vehicle. The bigger issue to worry about is the extraneous parts, such as the fuel pump (primary or low-pressure and secondary or high-pressure). Diesel is primarily an oil, which helps cool and lubricate the parts it comes in contact with. Those ...

If the engine consumes all the diesel in the tank, it also consumes the dirt/leavings from the diesel that tend to accumulate at the bottom of the tank. The dirt will go into the engine and into the alimentation circuit and a clearing will be needed because dirt may hinder the circuit. Also, if you run out of diesel there won't be any more in the circuit ...

As already stated, the ignition source between gasoline/gas engines and diesel engines are different and this is the primary reason for the difference in sound. I will try to explain those differences so you you'll understand why the sound is there with one, rather than the other. NOTE 1: There is a diatribe here, but bear with me as I attempt to answer the ...

The components which make up the exhaust note are the air, fuel, compression ratio, valve timing, exhaust, turbocharging, and displacement. The engine in the Cruze Diesel has a compression ratio around 16:1. The fuel is important, because diesel and petrol burn differently. The combination of all these factors is what results in the different exhaust ...

The biggest factors that makes a diesel sound the way it does is the method by which the diesel is injected into the cylinder prior to/during compression and the fact that their compression ratio is so much higher than a gasoline/petrol engine. This is a roundabout way of saying that the compression-ignition causes the characteristic sound. Secondary factors ...
