🚗 Vehicle Maintenance Isn't What It Used To Be...
Ever wonder why your grandfather changed his oil every few thousand clicks, but your owner's manual says much longer?
It's because the technology has changed.
Today's vehicles use components and fluids that simply didn't exist decades ago.
🔧 Spark Plugs
Copper plugs often lasted around 50,000 km.
Modern iridium plugs commonly last between 140,000km and 160,000 km.
🛢️ Engine Oil
Older conventional oils broke down much faster so they were changed out more often.
Today's synthetic oils resist heat better, stay cleaner longer, and protect modern engines far more effectively.
This means the typical 5000km oil change can last sometimes up to 15,000km according to manufacturers. (We don't recommend this as WE aren't trying to sell you a new car every 6 years 😉)
⚙️ Transmissions
Traditional automatic transmissions have very different maintenance needs than today's CVTs or dual-clutch transmissions. Using the wrong fluid—or skipping maintenance altogether—can become a very expensive mistake. Automatic transmission fluid typically lasted around 90,000km. Modern CVT transmission owners will commonly find the service interval closer to 45,000km.
🧊 Coolant
Many older vehicles required coolant changes every couple of years.
Modern long-life coolants can last much longer (7-10 years) —but they still don't last forever.
The bottom line?
Maintenance schedules evolve because vehicles evolve.
Following advice that worked on a 1995 pickup may not be the best choice for your 2025 SUV.
