If your car has some miles on it — we’re talking in the six figures — you’ve most likely been diligent about regular oil changes. If you hadn’t, your engine would have failed you long ago. And, over time, it seems that the oil you’ve been using has served your car well. But, it might be time for a change, especially if you’ve been using traditional oil. Now that your engine has been around the block a billion times, it’s in need of a stronger solution, namely high-mileage synthetic oil, to keep its engine running well.

“You can argue that your old car racked up 100,000 miles just fine with conventional car oil. Great. But now it has some wear on the piston rings, and it’s generating more ‘blow-by’ (combustion gas slipping by the piston rings). That increase in blow-by means more acid, soot, corrosion, varnish and sludge formation throughout the engine,” according to Family Handyman. “That’s precisely why switching to synthetic oil makes so much sense for older cars. The more robust additive package is especially well suited to keeping an older engine cleaner and running longer.”

If you’re hesitant to make the change due to the higher price tag associated with synthetic oil, the experts at Family Handyman note that it’s approximately a $10 increase per change. The extra cost now might save you from major repairs down the line or help ensure your engine runs longer than you ever thought possible thanks to the specialized ingredients designed to treat older engines.

“High-mileage synthetic oil contains film-strengthening additives to improve ring sealing and oil pressure. Many brands also include seal conditioners to soften stiff seals, as well as extra antioxidant, anticorrosion, antiwear and detergent additives to handle the crud in the crankcase,” according to Family Handyman.
