Premium helps keep your diesel engine clean.

Premium diesel contains detergents and additives that can prevent buildup and wear and tear on your engine parts. Cleaner parts means less downtime and less maintenance needed on your vehicle so you can keep it on the road longer.

It delivers more power and better fuel economy.

Tests have shown up to a 4.5% increase in engine power and 5% increase in fuel economy compared to using regular diesel fuel (source: AG Web). Due to its higher cetane rating (measurement of quality and performance of diesel fuel), it can promote quicker start-ups. Because premium diesel helps your engine run more faster, cleaner, and stronger, it can greatly improve your vehicle’s mpg (miles per gallon).

Compared to standard diesel, it works better.

Over time, your fuel pump and injectors can accumulate dirt, moisture, and other elements that can wear down your engine’s performance and reliability. Standard diesel doesn’t contain any additives that prevent corrosion, varnish and gum formation, and moisture accumulation – while premium diesel does.
