BMW Engine Performance

BMW Spark Plugs


Spark plugs could eventually die out or produce weak yellow spark rather than a purple spark which can cause misfire in an engine or poor acceleration. Weak spark can cause much more carbon deposits because gas doesn’t burn efficiently.


Regular Spark Interval – every 150,000 KM


Engine Oil


Engine oil is like blood in human veins, all BMWs uses special blend of synthetic oil. It is very important that oil is changed at regular intervals to keep VANOS system running at smoothly. Mechanic Nation uses special blend of oil that is imported from Dubai for high end cars, we use 5w-30 in all our imported cars that gives better protection meeting ISO standards.


Normal Service Interval is – every 8000KM


*some dealers / vehicles may take to 15000km ~ 25000km but interval is based on our repair experience in industry.
