The DIY Driveway Guide: How to Save Money on Car Maintenance Before Your Next MOT

If you want to save money on car maintenance, taking your vehicle to a main dealer or a major garage chain can instantly drain your wallet. But you don’t have to be a master mechanic to keep your vehicle running smoothly.

I consider myself a basic DIY enthusiast. I’m good with my hands, but my real secret weapon is using YouTube and car forums to figure out how to fix things myself instead of running to a garage. Leaning into basic DIY is easily one of the best ways to learn how to save money on car maintenance.

If your MOT or annual service is coming up, you can save a massive amount of cash by checking and replacing a few simple components right in your own driveway. Here is exactly what I do to prep my household vehicles and bypass extortionate garage labour rates.

1. How to Save Money on Car Maintenance with Basic DIY Servicing

Doing your own basic servicing sounds intimidating, but it is highly rewarding.

• The Oil Change: I tend to do my own oil and oil filter changes before my MOT is due. Now, this can be a bit tricky depending on your vehicle make and model, and you do need the right tools—specifically gloves, a hydraulic trolley jack, and sturdy axle stands to work safely. There are endless step-by-step guides on YouTube for your specific car to show you the ropes.
• The Air Filter: If an oil change feels like too big a leap, start with your engine air filter. On my car (a 2007 Toyota Auris), it is incredibly easy. It’s literally a case of popping open the bonnet, undoing four or five simple clips, pulling out the old dirty filter, dropping the new one in, and clipping it back shut. No tools required, and it takes less than two minutes!

2. Don’t Let Your Tyres Fail Your MOT

Tyre depth is a classic, frustrating reason for an MOT failure. If you fail at the test center, you’re stuck running around trying to get a tyre replaced in a hurry.

To prevent this, I do a regular visual check of my car tyres at home. I bought a tiny tyre tread depth checker tool online for less than £5, and it gives me an instant, accurate indicator of how much life is left. Checking tread depth early is an effortless trick to save money on car maintenance before minor issues trigger costly re-test fees.

💡 Money-Saving Tip: If you do need a new tyre, skip the massive mainstream fast-fit organizations. I always go to my local independent tyre fitter here in Birmingham. Their prices are almost always better, and the level of personal service is top-notch.

3. Wiper Blades and Bulbs (The Easiest Fixes)

Wiper blades and blown bulbs are incredibly common MOT failures, yet they are the easiest things to fix yourself. My wife’s car actually failed its MOT on wiper blades a couple of years ago, and changing them out is a breeze because most replacements use universal fitments.

I also recently had a front headlight bulb go out. Main stream retailers can charge a premium for parts and fitting, but I looked up my bulb size online and went down to a local independent parts supplier. I snagged a brand new bulb for just £2.50!

Replacing it required absolutely zero tools—I just unbolted the plastic cap behind the headlight unit from inside the engine bay, unscrewed the old bulb, and popped the new one in. Sourcing bulbs and wiper blades online proves that learning how to save money on car maintenance doesn’t require technical expertise.

4. Know Your Limits When Trying to Save Money on Car Maintenance

Part of saving money safely is knowing when to call in the professionals. For example, if you start hearing a squeaking or hissing noise when you press the pedal, your brake pads or discs need urgent attention.

Personally, I have never done brake components myself because I’m just not confident handling them yet. For major safety items like brakes, I always take my car to a trusted local independent garage.

How to save cash at the garage:

• Look for Google Reviews: Skip the main dealer. Find a local independent garage with great Google reviews. They care deeply about their local reputation and will go out of their way for you.
• Source Your Own Parts: If you trust your local parts supplier, ask the garage if you can source the correct components (like the exact brake discs or pads) yourself. If they agree, buying the parts direct can save you a tidy sum on the garage’s markup.
• Top Up Fluids: Before you even drive to the MOT center, fill your screenwash to the brim. Testers check this, and you don’t want to be charged garage prices for fluid top-ups!

Knowing when to delegate complex repairs helps you save money on car maintenance safely without putting your vehicle at risk.

What are your driveway tips?

By pre-checking your tyres, swapping your own bulbs, and keeping your fluids topped up, you’ll slide through your next MOT with far less stress on your mind and your bank account.
