Auto Maintenance FAQs

How often should I get my battery changed?
The cold dark mornings have crept back into our daily lives, and once again, our cars are bearing the brunt of the frosty weather and becoming sluggish as we head deeper into winter. It’s a common occurrence as low temperatures can cause your car battery to produce less current, making it that much harder for your engine to turn over in the morning. The cold can also stop your engine oil from flowing as well as it should, which puts even more strain on the battery. Essentially, cars and cold don’t get on well.
We do logbook servicing but do I keep my warranty?
Yes we fill out your service book and all manufacture warranty is keep as normal.
Do I need to charge my oil after 12 months
For a long time and sometimes still today, standard practice at many lube shops is to suggest oil changes every three months or 3,000 klms. In order to know when the best time to get your oil changed is, check the owner’s manual of your specific model for manufacturer-recommended intervals.
How do I know when I need new brakes?
You will feel in the brake pedal when the pads or discs are worn-out but it is best to let the professionals look at it first.
