  Type
                                                           -   Classification: API TC
  STIHL HP Ultra is a completely synthetic high-
  performance engine oil for use in air-cooled two-
  stroke and STIHL 4-MIX® engines in all climate           Applications
  zones.                                                   Engine oil approved exclusively by STIHL for
                                                           engines with gasoline-oil lubricating systems – with
                                                           or without catalytic converter.
  Mix ratio
                                                           STIHL HP Ultra is formulated for use in air-cooled
  50:1 (1 US gal. gasoline to 2.6 US fl.oz. engine oil).
                                                           high-performance engines with gasoline-oil
                                                           lubricating systems. Such engines require a high
  Properties                                               efficiency lubricant and are often operated for long
                                                           periods at full throttle.
  STIHL HP Ultra combines excellent lubricating
  properties with reduced carbonization. This
  distinguishes STIHL HP Ultra from many other             Mixing with Other Oils
  engine oils.                                             STIHL HP Ultra may be used in air cooled mix
  Benefits of STIHL HP Ultra:                              lubricated engines that have previously used other
                                                           types and brands of two-stroke engine oils.
  -   Excellent lubicating properties and high wear
      resistance.
  -   Suitable for engines with catalytic converter.
  -   Significantly reduced tendency to coke up the
      combustion chamber and exhaust system,
      which ensures consistently high engine power.
  -   Very good self-mixing properties.

Disposal
If necessary, the old or adulterated engine oil can be
added to other waste oil from four-stroke engines.

Important Information on Preparing                        Packaging
and Storing Fuel Mix                                      STIHL HP Ultra is available as follows:
.   Use a mid-grade gasoline with a minimum
    octane rating of 89 (R+M/2).                           Size of Pack                      Part #

.   Do not store fuel mix for long periods. The            2.6 US fl.oz bottle,
    mixture may separate, especially if fuels with a       48/Case                           0781 313 8004
    high alcohol content are used. This applies            5.2 US fl.oz bottle,
    particularly at low temperatures and if                48/Case                           0781 313 8007
    condensation gets into the mixture – the fuel          6.4 US fl.oz bottle,
    itself then segregates (alcohol separates from         48/Case                           0781 313 8010
    the gasoline). This process cannot be reversed         12.8 US fl.oz bottle
    even if the temperature rises again. The use of        24/Case                           0781 313 8013
    such a segregated fuel mix results in engine           1 US gal. bottle,
    running problems and may cause engine                  6/Case                            0781 313 8015
    damage.
                                                           5 US gal. pail                    0781 313 8016
.   Storage life of fuel mix: approximately 3 months.      55 US gal. drum                   0781 313 8017
.   Fuel mix that has been stored for a long period
    should be shaken or agitated vigorously before
    use.
