As engines age, oil consumption often increases. Worn seals, deposits, and thinning conventional oils make the problem worse in high-mileage vehicles. Preventive maintenance with AMSOIL synthetic oils reduces oil consumption, extending engine life and saving drivers money.

Why Older Engines Burn Oil

High-mileage engines develop worn seals and rings, allowing oil to enter combustion chambers. Conventional oils break down quickly, making leaks and burning worse. Deposits around seals harden them, further increasing oil consumption.

Synthetic Oils Solve the Problem

Synthetic oils condition seals, restoring flexibility and reducing leaks. Their detergents dissolve deposits, helping rings and seals operate properly. With stronger film strength, synthetic oils resist burn-off at high temperatures, reducing oil loss through evaporation.

AMSOIL Products That Reduce Consumption

AMSOIL High-Mileage 10W-30 Synthetic Motor Oil is formulated to protect aging engines while reducing oil consumption. It resists volatility, keeping oil where it belongs. AMSOIL Signature Series Synthetic Motor Oil provides additional protection with extended drain intervals. For drivetrains, AMSOIL Severe Gear® Synthetic Gear Lube reduces leaks and protects components under stress.

Preventive Maintenance Checklist

Drivers of high-mileage vehicles should:

• • Change oil regularly with AMSOIL synthetic oils.
  • Replace clogged PCV valves to reduce pressure buildup.
  • Inspect seals and gaskets for wear.
  • Use AMSOIL P.i.® to keep injectors clean for efficient combustion.

Benefits for Drivers

Lower oil consumption means fewer top-offs, cleaner emissions, and reduced repair costs. Drivers can trust their older vehicles longer with preventive maintenance supported by AMSOIL products.

Oil consumption doesn’t have to end a vehicle’s life. AMSOIL synthetic oils reduce leaks, resist burn-off, and keep engines protected. Preventive maintenance with AMSOIL extends the useful life of high-mileage vehicles.
