Recommended Posts

Only have used the stihl red, use a fuel stabilizer and pretty much follow Stihls recommendations as reproduced below and have had no problems. Interesting their comment about using the HP Ultra oil with E10 petrol:

 

If the proper precautions are taken, however, gasoline containing a 10% quantity of ethanol can safely be used in your STIHL products.

 

• Use a minimum of 89 octane gasoline and always use fresh fuel. Only buy enough gasoline that you can easily use up within a two month period.

 

• For air-cooled, two-cycle engines, use a quality mix oil that meets the engine manufacturer’s recommendations. All STIHL oils are designed to readily mix with gasoline containing 10% ethanol. STIHL HP Ultra Oil is especially suited for use with E10 gasoline.

 

• Shake your gas can well when first mixing the oil to thoroughly disperse the oil in the fuel mixture.

 

I think Stihl Green already has a stabiliser in it. :001_smile:

Why is that?

 

We have had more than enough customers that have switched from hp red to super or a husky equivalent oil and would never look back.

 

Why pay for BIO ? Never had issues with quality 2 stroke oil so why pay a premium , worked on plenty of seized huskys running XP , some could be put down to fuel quality issues but the XP never saved them .

You were lucky. Latest gen autotune saws from S,H and D all state NOT to use mineral base 2 cycle oil in these engines.

 

Seems reading the instruction / owners manual is a lost art.

 

In the Husky manual it did say use Synth oil but if using mineral oil to the Sthil spec use is at 33 to 1 ( might be 25 :1) as opposed to 50 to 1.

 

The supplying dealer has sold me the saw and the oil at the same time, they had never heard of syth 2 stroke oil and they are a fair sized dealer for all the major brands.

 

But have only used Synth since.

Two-stroke oil

• For best results and performance use HUSQVARNA

two-stroke engine oil, which is specially formulated for

our air-cooled two-stroke engines.

• Never use two-stroke oil intended for water-cooled

engines, sometimes referred to as outboard oil (rated

TCW).

• Never use oil intended for four-stroke engines.

• A poor oil quality and/or too high oil/fuel ratio may

jeopardise function and decrease the life time of

catalytic converters.

Mixing ratio

1:50 (2%) with HUSQVARNA two-stroke oil.

1:33 (3%) with oils class JASO FB or ISO EGB formulated

for air-cooled, two-stroke engines

Designed to meet all the tough challenges 2-stroke engine oil can encounter Husqvarna HP 2-stroke oil is also formulated to work well with low-quality fuels. The additives are of highest quality and are especially chosen to lessen deposits an the crankcase which can arise from using low-quality fuel. The oil is designed to suit the entire product range of our 2-stroke products – from the smallest trimmer used all day up to the biggest chainsaw used for heavy felling and limbing in extremely hot or cold conditions.

Usually the main reason is because it's fully synthetic. Although we do have a few customers who use it because it's biodegradable, wild life trusts etc.

 

Tbh I wouldnt expect any oil to save an engine if there are other issues, ie poor fuel or air leaks etc.

 

It is only an extra 60p per 5 litres of fuel so imo its worth the extra cost to use fully synthetic oil.

Yes i sell Aspen synth 2 stroke oil to a few customers requiring Bio oil , i see you sell Echo Power blend ,very high ratings from users in the States .

From my own observations the Bio Synth oils have yet to sway me due to there inability to stave off rust in standing machines .
