Hi Arvind,

The work to change the oil and filter in that Skoda is little different to the same job in any other car, but we'd not recommend it is done by someone without experience unless supervised by someone that has. There are lots of things that can go wrong in the process that could lead to engine damage and further costs, which would massively outweigh the savings made by not going to a professional in the first place. 

If you are determined to do it, here is a generic step-by-step set of instructions that could be applied to most cars, and it's written on the assumption that the car is safely raised on a proper vehicle lift:

- With the lift lowered, turn off the ignition, remove the keys and pop the bonnet.

- Remove and clean the dipstick and remove the oil filler cap. Make sure nothing can fall into the hole.

- Raise the lift so you can comfortably walk under the car and reach the underside of the engine.

- With a suitable collecting recepticle to hand, locate the oil sump plug and remove it. The dirty used oil will start to flow before it is fully out so be prepared for that.

- Once the flow has clearly slowed to a tricikle, locate the oil filter. On some cars this will be accessible from above the engine, in others, below. On some cars, it will be a cartridge within a permanent outer casing, on others, an aluminium-skinned component that screws off in its entirety. It's highly likely you'll need a special oil filter removal tool to take it off. Most of the time, a small amount of dirty oil will leak out, so be prepared to collect that under the car.

- Check the new oil filter against the old one. In particular, the sealing rings must be in an identical position.

- Fit new oil filter tightly to recommended tightness.

- It's often a good idea to fit a new oil sump washer at this stage, then tighten up the sump plug to the recommended tightness and give everything a wipe down.

- Lower the car again and fill with new oil to about a litre less than the official full level. Replace the dipstick and oil filler cap.

- Start the engine without revving it, let it idle a minute, then turn it off again.

- Check the oil level with a cleaned dipstick and top up as necessary.

Hi Andy,

All three are good cars (and reliable too, with the Octavia at the top of the pile in that respect, the Mondeo second and the Insignia third). The Mondeo is the best to drive, and has the most interior space, but the Octavia actually wouldn’t be far behind, and has good seats. If cabin space is your thing, the Insignia comes off worst — it’s quite small in there, unless you’re talking about the new-shape model, introduced in 2017, which is actually very roomy.

Hi Joe,

Assuming you mean the 150hp 2.0 TDI model, the change interval is every 210,000 kilometres, regardless of age. I'd suggest that you treat that as a maximum and no harm getting it done a little early.

Hi Mark,

Well, it is — in effect — impossible for us to say with any authority as to how the 1.0 TSI engine is going to perform in the longer term, as the engine hasn’t been around all that long. What we can say is that, so far, there have been no horror stories emerging of any major reliability issues, and that Skoda has (a) good quality control systems and (b) a good reputation for high quality and reliability. After all, when people ask about the most reliable cars, we generally say Japanese, Korean and Czech — in that order. As long as you keep it properly serviced, I don’t think you’ll have any major problems.

Hi John,

Yeah, it’s a bit of a catch-22 at the moment. The thing is that diesel is still entirely viable if you’re someone who covers a big annual mileage. Petrol makes the most sense for those covering short mileages, and primarily driving in town; ditto hybrid, while electric mostly only makes sense for those doing entirely urban mileage.

So, if you live down the country and rack up at least 25,000km a year, then diesel could still work for you. If you’re struggling to find a good second hand petrol car, it may be worth looking at buying new, and trying to find a really sharp finance deal.

Hi Angela,

An absolutely cracking car, and a great combination of car and engine. The 1.0-litre TSI petrol engine is smooth and economical, and really does suit the Octavia very well indeed. The specification is decent, especially if you’re buying an Ambition model or above, and make sure you spec it with the eight-inch touchscreen, as that really lifts the ambience of the cabin. Fuel economy should work out at between 40mpg and 50mpg on average, depending on how you drive it.

Hi James,

The 2015 Skoda Octavia 1.2 TSI petrol uses a timing belt that must be changed at least at 240,000km first, and then every 30,000km after that, regardless of time.

It's the same interval for the 1.0 TSI engine's belt. It has only been in production since 2016 so there isn't a lot of data, but we've not heard about any issues with it.

Hi Hago,

Of the three you’ve mentioned, we’d discount the SX4 first. It’s a decent car, but a bit tiny and noisy for long motorway hauls. A Mazda3 would be much better, and hugely reliable, but the Skoda will have a slight edge in terms of comfort (really good seats) so go for one of those would be our advice.

Hi Peter,

In this instance, the sales people are being entirely truthful — the new 1.0-litre turbo engines are indeed equivalent to an old 1.6 or even 1.8 engine in the way they drive. You certainly won’t find them too ‘revvy’ on the motorway, as the small turbo increases low-down torque and makes the car feel very relaxed and easy to drive. Certainly that’s true for the Volkswagen Group, Ford, Honda and Renault-Nissan engines anyway. The best ones to go for, in our experience, are the VW Golf or Skoda Octavia (both using the same engine, of course), the Honda Civic (which should be the most reliable in the long term) and the Ford Focus (which can be a little on the thirsty side).

Hi Jan,

I'm not sure if your mechanic has actually driven the Octavia with the 1.0-litre engine, but we have and it's brilliant. If you had five adults inside and a boot full everywhere you went, it might not feel too quick, but otherwise it's more than adequate. In fact, we've done a full review and video review of that very car if you want to check it out:
