Ever wondered what goes into keeping your car’s engine running sweet as, especially around Hamilton—what with all the stop-start driving, potholes out in places like Flagstaff, and those crazy temperature swings between foggy mornings and scorching summer afternoons down Te Rapa Straight? One of the little tricks we use here at Grimmer Motors is motor oil additives. They’re not some fancy snake oil. They’re practical helper-ons for your engine that work with the oil to sort out common NZ car problems and keep things humming along.
What Are Motor Oil Additives, Anyway?
Basically, when we do your regular oil check or oil change (why do you need those, anyway?), sometimes we recommend these extras—additives that mix in with your oil and help deal with stuff your engine cops from local roads and driving style. Whether you’re running a Toyota Corolla, a Honda Fit, a Nissan Dualis, or something European like a Peugeot 308 or Skoda Octavia, you’ll benefit from the right mix.
Why We Might Add Stuff to Your Oil
Cut Down on Exhaust Smoke
If you spot blue or grey smoke puffing out the back while you’re crawling through Five Cross Roads in traffic, or waiting at the green in Rototuna, there might be a bit too much oil sneaking past your engine seals. Happens a bit with older Mazdas and even some hybrid repair jobs we see (Prius, Aqua—you name it). We’ll often add a special stop smoke additive to your oil to help you breeze through your WOF Hamilton, especially because excessive smoke’s a big fail point.
Protect Against Wear and Tear
Hamilton roads aren’t kind—think of the ruts around Dinsdale and those speed bumps all over Cambridge. Your engine’s got heaps of moving parts scraping away together. We use friction modifiers in the oil to keep everything gliding, cut down chatter, and help engines last longer without needing those big, scary repairs. Had a Suzuki Swift or a Citroen C4 in lately with noises that quietened right up after a service.
Stop Rust and Corrosion
Corrosion’s a killer for engines, especially if you don’t get out for longer runs between Cambridge, Taupiri, or Morrinsville. If oil gets too thick and sludgy, rust starts creeping in. Antioxidant additives go in to keep things flowing well and stop the gunk that leads to corrosion. Handy for cars that mostly do short runs—think the runabout used to get the kids around.
Keep Oil and Engine Clean
Short commutes and city driving mean your oil can get dirty fast. Detergent additives pull grime and carbon out, so it doesn’t settle inside your engine. We did this for a woman’s Hyundai Ioniq recently—she mostly drives between Hillcrest and Glenview, lots of short trips. Along with dispersants, these additives keep the insides clean and protect from rust and sludge build-up.
Keep Oil the Right Thickness
Your oil’s got to work whether you’re starting up on a frozen Frankton morning or stuck in summer jams along Peachgrove Road. Viscosity blend in the oil keeps it just right—thin enough for winter mornings, thick enough for summer heat. This is a big one for European cars like an Alfa Romeo Mito or Subaru Outback that seem fussy about their fluids.
No Foaming
Seen bubbles in the oil when a technician checks the dipstick? That foaming stops oil doing its job. Really common in a few high-rpm or turbo cars (like VW Golfs we get from Tamahere). Anti-foamants deal with that so the oil stays smooth and keeps on lubricating.
