Quick answer: Liqui Moly Motor Oil Saver is the top pick to curb oil burn.
You check your dipstick and it’s low again. The oil light nags. The tailpipe smokes a bit on startup. I’ve been there. Small leaks, tired valve seals, or worn rings can make an engine sip oil between changes. The right oil additive can slow that loss, reduce smoke, and even quiet ticking. In this guide, I break down the best additive for oil consumption for different engines and budgets. I looked at viscosity boosters, seal conditioners, and friction modifiers that target how and why engines burn oil.
