STIHL HP Super 2-Stroke Engine Oil - Semi-Synthetic Oil for STIHL 4-MIX and 2-Stroke Engines
STIHL HP Super 2-Stroke Engine Oil (part number 0781 319 8068) is a premium semi-synthetic 2-stroke oil developed specifically for mix-lubricated two-stroke engines and STIHL 4-MIX engines in handheld power tools. Formulated with low-ash additives and a semi-synthetic base, HP Super meets the JASO-FD and ISO-L-EGD performance classifications — the high-detergency, low-smoke standard for 2-stroke oils — and is mixed at a 50:1 fuel-to-oil ratio (100ml per 5 litres of petrol). Compatible with all STIHL petrol 2-stroke tools including chainsaws, brushcutters, hedge trimmers and disc cutters, and particularly recommended for STIHL 4-MIX engines where its higher detergency helps maintain clean valve and port operation. Available in 100ml single-shot bottles and 1L from Gustharts, an authorised STIHL dealer with UK stock ready to ship.
HP Super burns cleanly and with low smoke, reducing deposits in the combustion chamber, piston head, exhaust ports and muffler — helping maintain consistent engine power and extend service life over long working periods at full load. Not for use in 4-stroke engines where mixed lubrication is not part of the engine design (such as STIHL lawn mowers and tillers, which require SAE 30 engine oil).
Key Features
- Semi-synthetic formula with low-ash additives — cleaner burning than mineral-base 2-stroke oils, with reduced combustion chamber and port deposits
- JASO-FD, ISO-L-EGD performance classification — high-detergency, low-smoke standard for 2-stroke and 4-MIX engines
- 50:1 fuel-to-oil ratio — 100ml single-shot bottle pre-measured to treat 5 litres of petrol accurately on site
- Particularly recommended for STIHL 4-MIX engines — higher detergency supports clean operation of valve gear under the mixed-lubrication regime
- Suitable for all STIHL 2-stroke petrol tools — chainsaws, brushcutters, hedge trimmers, disc cutters, clearing saws and strimmer models
- Low-smoke combustion — meets ISO-L-EGD low-smoke oil classification for reduced emissions and cleaner working environment
- Full-load performance — strong film strength for extended periods of high-RPM, high-demand engine use
- Genuine STIHL OEM oil — formulated to match STIHL engine metallurgy, tolerances and additive requirements
- Available in 100ml single shot and 1L — suited to single-tank mixes or bulk workshop use

Understanding JASO-FD and ISO-L-EGD
JASO (Japanese Automotive Standards Organisation) ratings define performance tiers for 2-stroke engine oils. JASO-FD is the highest tier in the JASO 2-stroke classification system, requiring superior detergency, lubricity and cleanliness compared to lower JASO-FB and JASO-FC ratings. It is the standard specified for modern, high-performance 2-stroke engines and mixed-lubrication engines where deposit control is critical.
ISO-L-EGD is the International Standards Organisation classification for low-smoke 2-stroke oils. An oil carrying the EGD designation produces significantly less smoke and exhaust residue than standard EGB-rated oils, and must pass stricter limits for engine cleanliness, lubrication film performance and combustion by-products. Together, JASO-FD and ISO-L-EGD confirm HP Super is a high-detergency, low-smoke oil suited to demanding professional use.
HP Super vs HP vs HP Ultra - Which STIHL 2-Stroke Oil Do You Need?
STIHL produces three 2-stroke engine oils at different performance tiers. Choosing the right one depends on your engine type and working conditions.
| Feature | HP | HP Super | HP Ultra |
|---|---|---|---|
| Oil type | Mineral | Semi-synthetic | Fully synthetic |
| Performance class | JASO-FB, ISO-L-EGB | JASO-FD, ISO-L-EGD | JASO-FB, ISO-L-EGB |
| Detergency level | Standard | High (FD) | High (ash-free) |
| Smoke level | Standard | Low smoke (EGD) | Extremely low residue |
| 4-MIX recommended | No | Yes — particularly recommended | Yes |
| Best suited for | Standard 2-stroke use, occasional use | 4-MIX engines; extended full-load professional use | Most demanding conditions; used in STIHL MotoMix |
| Fuel ratio | 50:1 | 50:1 | 50:1 |
If you run a STIHL 4-MIX engine (found in selected FS brushcutter and strimmer models) or regularly work at full load for extended periods, HP Super is the correct choice. If you need the absolute highest specification for the most demanding conditions or want to use a pre-mixed fuel solution, HP Ultra is the top tier. Standard HP is suited to occasional and light domestic use on conventional 2-stroke engines.

Mixing Guide
Mix at 50:1 — one 100ml single-shot bottle per 5 litres of fresh unleaded petrol (minimum 89 RON). Always add oil to the fuel container first, then add petrol and shake to mix thoroughly before filling your machine. Use a calibrated STIHL mixing bottle for accurate ratios when mixing from a 1L container. Do not store mixed fuel for more than 30 days unless using a fuel stabiliser — stale mixed fuel is a common cause of starting and running problems in STIHL 2-stroke tools.
Important Use Guidance
Not for 4-stroke-only engines. HP Super is for mix-lubricated 2-stroke and 4-MIX engines only. Do not add it to the engine oil sump of a 4-stroke engine such as a STIHL lawn mower or tiller — these require STIHL SAE 30 engine oil.
Use fresh petrol. UK pump petrol containing more than 10% ethanol (E10) can degrade over time. Mix only what you plan to use within 30 days, or switch to STIHL MotoMix premixed ethanol-free fuel for longer storage life.
Maintain the correct 50:1 ratio. Too little oil risks engine seizure; too much oil increases smoke, deposits and spark plug fouling. Use the single-shot 100ml bottle for a foolproof 50:1 mix with 5 litres of fuel.
Dispose of unused mixed fuel and oil responsibly. Take to a designated used oil or hazardous waste collection point at your local civic amenity site. Do not pour down drains or onto the ground.
Also Known As
STIHL HP Super 2-Stroke Engine Oil is also referred to as semi-synthetic 2-stroke oil, 2T oil, two-stroke mix oil, chainsaw oil mix, strimmer oil, 4-MIX engine oil and STIHL green oil (the bottle is green, distinguishing it from the red HP and blue HP Ultra). For ordering and parts identification, always use STIHL part number 0781 319 8068 — also formatted as 07813198068 and 0781-319-8068.
Often Replaced Alongside
When topping up or completing a service on a STIHL 2-stroke or 4-MIX tool, it is worth checking these at the same time:
- Spark plugs — replace at standard service intervals or if starting and running problems are linked to plug condition
- Air filters — blocked air filters are a common cause of running problems; inspect alongside every oil purchase
- STIHL chain oil — if purchasing HP Super for a chainsaw, bar and chain oil will also need topping up

FAQs
What is STIHL HP Super 2-stroke oil used for?
HP Super is used in all STIHL mix-lubricated 2-stroke petrol engines and is particularly recommended for STIHL 4-MIX engines. It is not for use in 4-stroke-only engines such as lawn mowers or tillers.
What is the part number for STIHL HP Super 2-stroke oil?
The UK part number is 0781 319 8068, also formatted as 07813198068 and 0781-319-8068.
What sizes is STIHL HP Super available in?
Available in a 100ml single-shot bottle (pre-measured for 5 litres of petrol at 50:1) and a 1L bottle for workshop or multi-tank use.
What is the difference between STIHL HP, HP Super and HP Ultra?
HP is mineral-based (JASO-FB). HP Super is semi-synthetic with higher detergency (JASO-FD) and is particularly recommended for 4-MIX engines. HP Ultra is fully synthetic with ash-free additives for the most demanding conditions and is used in STIHL MotoMix.
What is a STIHL 4-MIX engine and why does it need HP Super?
4-MIX is STIHL's engine technology combining 2-stroke and 4-stroke principles, with fuel mixed with oil lubricating part of the engine. HP Super's JASO-FD detergency helps keep valve gear and ports clean under this mixed-lubrication regime.
What is the correct mixing ratio for HP Super?
50:1 — one 100ml single-shot bottle per 5 litres of fresh unleaded petrol (minimum 89 RON). Always add oil to the container before petrol and mix thoroughly.
Can I use HP Super in a non-STIHL 2-stroke engine?
Yes. Any engine requiring a JASO-FD rated 2-stroke oil at 50:1 will be compatible with HP Super. Check your machine's manual for the required specification and mix ratio before use.
How long can I store mixed STIHL HP Super fuel?
Mixed fuel should ideally be used within 30 days. For longer storage, use STIHL MotoMix premixed fuel, which can be stored for up to five years. Stale mixed fuel is a common cause of starting and running issues in 2-stroke tools.
