MAX-TANE®

Royal Purple® Max-Tane® is formulated for year-round use in all types of light, medium and heavy duty diesel engines, and is compatible with any type or grade of diesel fuel, including #1 diesel and #2 diesel, biodiesel and ultra-low-sulfur diesel (ULSD). Max-Tane is specifically formulated to solve problems associated with today’s new HPCR (High Pressure Common Rail) diesel injection systems. Safe for use with all types of diesel exhaust emission systems equipment, including diesel particulate filters (DPFs) and catalytic converters. Do not pour into Diesel Exhaust Fluid.

Key Benefits

  • Increases Cetane Number by up to 8*

  • Increases fuel economy by up to 10%

  • Improves cold flow by preventing gelling

PERFORMANCE ADVANTAGES

  • Increases Cetane Number by up to 8*
  • Increases fuel economy by up to 10%
  • Improves engine startup and reliability in both warm and cold temps
  • Improves cold flow by preventing gelling
  • Cleans deposits from fuel injectors, combustion chambers, intake valves and piston crowns
  • Provides lubricity to entire fuel system
  • Reduces smoke and odor* When used as directed.

RECOMMENDED TREAT RATE

The minimum recommended dosage is one (1) ounce per five (5) gallons of diesel fuel. High performance applications can safely use one (1) ounce per two (2) gallons of diesel fuel for maximum benefit. If uncertain of exact tank size, round up. Replace cap after bottle has been emptied and dispose of properly.

20 Ounces – 100 Gallons

15 Ounces – 75 Gallons

10 Ounces – 50 Gallons

5 Ounces – 25 Gallons

Higher cetane allows quicker ignition of diesel, which boosts power/ performance and improves completeness of combustion. With less non-ignited hydrocarbons inside the combustion chamber, deposit formation is reduced. Optimized combustion also results in faster cold startups, smoother and quieter engine operation, reduced downshifts, less soot/black smoke production, reduced emissions, and improved fuel economy. Max-Tane provides maximum cetane boost as it contains 100% active ingredients, and unlike other products is not blended with inactive solvent carriers.

Diesel particulate emissions are captured by the DPF, where they accumulate and cause clogging unless burned off during regeneration cycles. With improved combustion efficiency, less particulate soot accumulates in the DPF, requiring fewer regenerations. Cleaner filters also reduce exhaust backpressure, allowing efficient engine operation and reduced temperatures. Stop-and-go urban driving causes incomplete regenerations, which can require removal/manual cleaning or replacement of DPF. Max-Tane keeps DPFs clean and helps prevent costly downtime resulting from manual cleaning or replacement of DPF.

High Pressure Common Rail (HPCR) diesel injectors are vulnerable to fuel contaminants due to extremely tight 1-3 micron clearances between injector assemblies and needle plungers. When deposits form, needle plungers stick, resulting in reduced fuel atomization and 5-12% losses in fuel economy. Max-Tane contains potent, diesel- specific detergents that keep HPCR injectors clean and deposit-free. It also contains friction modifiers that prevent sticking of HPCR needle plungers. This allows complete atomization of diesel entering combustion chambers, and restores lost fuel economy.

Wax naturally found in diesel forms gels in cold temps, which clogs filters/injectors, and prevents engines from starting. The temperature at which gel begins to clog the fuel filter is the “Cold Filter Plugging Point” or (CFPP). Max-Tane reduces CFPP an average of 28°F., which allows diesels to reliably start/run in the cold temperatures. Max-Tane is the only “All-in-One” additive that combines summer benefits of cetane boost and fuel economy improvement with the winter benefit of CFPP reduction.

    i have only been through half a bottle but so far seems to live up to the Royal Purple name.

  • 5star

    I’m a big fan of using powerservice at every fill up to protect the CP4 on my truck and for the small boost in fuel economy. Max-Tane is 10 times better. It routinely will give me 2 more MPG’s and it smooths out the idle of my 6.7, not to mention the fact that its loaded with good detergents to keep everything clean.

    Have used this product for several years in my Ram 3500 diesel.

  • 5star

    Excellent mileage & performance to preserve fuel & get quality long range driving

  • 5star

    i run this in my 04 F350 with a 6.0 …..have for over 14 years every tank….has 360 K on it no fuel related issues great power,, filters always clean,,…. highly recommend any deisel

  • 5star

    Immediate results. I will definitely use again. I put a little bit in the filter housing under the hood and put a littile in the tank. There are reviews that people moan and groan about the “short” neck of the bottle…some people Will try to hard to complain about ANYTHING!! All you need is a little common sense and there will be NO problem.

    Works great, had been using motokote Cetane Boost, but no longer. Get about a mile per gallon more than motokote, with royal purple.

  • 5star

    There are a lot of products that claim to improve milage. Added this to my fuel, before adding I was averaging about 17.5 mpg on my 06 Dodge Cummins. After adding this product I am averaging between 19.5 and 21.3 mpg.

    This stuff cleans your engine like as if it were brand new!

  • 5star

    I have a Jetta that had a check engine light (P401) and had the dealer replace the inlet manifold but that did not clear the fault. After running some more tests dealer gave me a quote for $2,400 to replace the emission system as there was a buildup of carbon deposits. Used Royal Purple and within 50 miles check engine was gone. Highly recommended.
