When it comes to versatility, Shell Rotella Full Synthetic Multi-Vehicle 5W-30 is in a league of its own. Unlike most oils that serve either gasoline or diesel engines, this one is designed for both.

Add to that its strong oxidation resistance, and you have an oil that not only keeps your engine clean but also helps it last longer.
Cold winters? No problem. Shell Rotella flows easily in freezing temperatures, making cold starts smoother. Plus, the brand backs its confidence with a 15-year or 500,000-mile warranty—whichever comes first. That’s not just a bottle of oil; that’s peace of mind in liquid form.
