How we shortlist
Every pick is an ASIN already in the comparison. The score weights amazon.co.uk stars and a capped allowance for the review count. It is not a laboratory score. Oregon’s 1 litre biodegradable oil and Rotatech’s 5 litre can both score 97. Oregon is 4.8 from 13,667 reviews at £11.13 per litre. Rotatech is 4.8 from 953 reviews at £4.40 per litre. The top pick stays with Oregon because the review base is far larger. Carlube XPM011 is best value at £3.69 per litre, with ISO 220, an anti-fling claim, and 4.7 from only 142 reviews.
A 4.9 from 46 reviews is not stronger evidence than 13,667 reviews, and a £4.49 bottle of 50 ml is £89.80 per litre. HSE INDG317 still keeps discarded engine oil out of the bar tank. Pack-size maths is on the chainsaw oil buying guide.
Best for regular petrol cutting
For a winter of firewood, buy volume you will finish. Stihl ForestPlus at £29.85 for 5 litres is £5.97 per litre, 4.8 from 798 reviews, 10W-40, score 96. Oil type and biodegradable are empty, so read the can if the site asks for bio. Ignore the 15°C flash point and the 1 kg item weight: both clash with 5 litres. Skip it if you need a bio line, or if the can will sit for years.
Rotatech is the biodegradable bulk alternative at £4.40 per litre, with anti-fling, 10W-30, and a listed weight of 4.1 kg. Skip it for a couple of afternoons. Carlube XPM011 on amazon.co.uk at £3.69 is the 1 litre ISO 220 option. Skip it for a bio job, for cap-leak worries in the review notes, or if you want thousands of reviews. Check the bottle title: its best-sellers line sits under automotive hydraulic oils.
Best biodegradable listing
The top pick for one biodegradable litre is Oregon, ASIN B002X3IDBK: Oregon biodegradable chainsaw oil, 1 litre. The listing claims biodegradable oil, anti-fling, and petrol and electric use, with a flash point of 250°C. Amazon reviews mention electric and mini saws, and the pouring spout. The item weight of 250 g does not describe a litre, so trust the 1 litre on the title. Skip Oregon if the handbook wants a printed ISO or 10W grade, because viscosity is blank, or if several litres make Rotatech’s £4.40 per litre the better spend.
Liqui Moly Bio, SKU 1280, lists 10W-30 and a 318°C flash point at £12.49, 4.7 from 2,369 reviews, with compatibility blank. BioPlus at £17.89 is the Stihl name; Stihl’s UK page refers to OECD 301 B. Synthplus at £11.99 is semi-synthetic and stays off this shortlist.
Best for cordless owners
A cordless saw still needs bar oil if it has an oiler. A 50 ml bottle looks handy and costs far more per litre: DD teck 50 ml is £4.49 (£89.80 per litre) and 100 ml is £6.29 (£62.90 per litre). The nozzles are £6.49 for 100 ml, 4.9 from 46 reviews, and £5.29 for 50 ml, £105.80 per litre from 21 reviews. Rows that share a 750-review count also share a rank, so count 750 once. Each DD teck row says mineral and biodegradable together. That is not an OECD-tested bio oil.
If you cut more than once, decant Oregon’s 1 litre, which states petrol and electric. Rotatech’s 5 litre can mentions electric or battery saws and wins on £4.40 per litre only if you will use it. Buy a nozzle when you are empty on the day. Filling checks are on how to fill chainsaw oil.
Common questions
What is the best overall bar oil in this comparison?
Oregon’s 1 litre biodegradable oil (ASIN B002X3IDBK) is the top pick: 4.8 from 13,667 reviews, score 97, £11.13 per litre, with biodegradable, anti-fling, and petrol and electric claims. Rotatech ties the score from 953 reviews and costs less per litre. The larger review base keeps Oregon in the single top-pick place. This is listing evidence, not a lab test.
What is the best value per litre?
Carlube XPM011, at £3.69 a litre with ISO 220 and an anti-fling claim, 4.7 from 142 reviews. Among bottles that claim to be biodegradable, Rotatech is £4.40 per litre if you can use 5 litres. A 50 ml bottle that looks cheap costs about £90 to £106 per litre.
What is the best biodegradable option listed?
Oregon at £11.13 for one litre and 13,667 reviews. Liqui Moly at £12.49 if you want 10W-30 on a bio bottle. BioPlus at £17.89 for the Stihl name and the manufacturer’s OECD 301 B reference. Rotatech at £4.40 per litre if you will finish 5 litres. Skip DD teck for a clean bio claim: those listings say mineral and biodegradable together.
Oregon or Liqui Moly bio?
Oregon if you want the larger review count, an anti-fling claim, and petrol and electric on the listing, at £11.13 a litre, with viscosity blank. Liqui Moly Bio if you want 10W-30 and a 318°C flash point, at £12.49 from 2,369 reviews, with compatibility blank. The spout comes up on both. A handbook grade breaks the tie.
Does best mean lab tested?
No. Scores use amazon.co.uk stars and review counts. Prices and claims come from those listings. HSE covers lubrication and the warning on waste engine oil, and it does not approve a brand. Top pick and best value are labels for this comparison. Recheck the live price and the ASIN on the can.
