Engine Oil

About Engine Oil

Engine oil is a vital lubricant for petrol-powered garden machinery and outdoor power equipment, including lawnmowers, chainsaws, strimmers, hedge trimmers, and generators. Proper lubrication reduces friction between moving parts, prevents overheating, minimises wear and tear, and significantly extends the operational life of your equipment. Whether you're maintaining professional landscaping tools or domestic garden machinery, selecting the correct engine oil is fundamental to reliable performance and longevity.

MyToolShed.co.uk stocks engine oils in two main categories: 2 stroke oil for engines requiring oil mixed with petrol (commonly found in chainsaws and strimmers), and 4 stroke oil for engines with separate oil reservoirs (typically lawnmowers and generators). Our range includes trusted brands such as ALM, Handy, and Makita, offering both convenient one-shot bottles for pre-measured mixing and larger containers for regular maintenance schedules. We stock mineral-based and semi-synthetic formulations suitable for various operating conditions, from light domestic use to demanding professional applications.

Applications

Engine oil for garden and power equipment is essential for a diverse range of users:

• Landscapers and groundskeepers maintaining commercial properties, parks, and estates
• Gardeners and horticultural professionals operating petrol-powered machinery daily
• Tree surgeons and arborists relying on chainsaws and climbing equipment
• Groundwork contractors using generators, pumps, and portable power tools on site
• Agricultural workers and farmers maintaining small engines across their operations
• Property maintenance professionals servicing multiple sites with various equipment
• DIY enthusiasts and homeowners maintaining domestic lawnmowers, strimmers, and garden tools
• Allotment holders keeping their petrol equipment in peak condition

Choosing The Right Engine Oil

Engine Type: The most critical decision is determining whether your equipment has a 2 stroke or 4 stroke engine. Two stroke engines require oil mixed with petrol, whilst four stroke engines have separate oil reservoirs. Check your equipment manual, as using the wrong type can cause serious engine damage.

Manufacturer Recommendations: Always consult your equipment's documentation for the specified oil type, viscosity grade, and performance standards. Premium brands often recommend specific formulations, though quality alternatives meeting the same specifications are generally suitable.

Usage Intensity: Professional tradespeople running equipment for extended periods should consider semi-synthetic oils offering superior protection under demanding conditions. Domestic users with lighter, intermittent usage may find conventional mineral-based oils perfectly adequate.

Convenience vs Economy: One-shot bottles from MyToolShed.co.uk provide pre-measured convenience ideal for occasional use, eliminating mixing errors. Larger containers offer better value for regular users maintaining multiple machines throughout the season.

Safety Information

Storage: Keep engine oil in its original container with the lid securely fastened, stored in a cool, dry location away from direct sunlight and ignition sources. Ensure oils are kept out of reach of children and pets.

Disposal: Never pour used engine oil down drains or into the ground. Used oil is classified as hazardous waste under UK environmental regulations. Take used oil to your local household waste recycling centre where dedicated collection facilities are provided.

Mixing 2 Stroke Fuel: Always mix 2 stroke oil and petrol in a well-ventilated area, away from naked flames. Add oil to the container before petrol, then shake thoroughly to ensure complete mixing. Label mixed fuel clearly and use within one month.

Frequently Asked Questions

Can I use car engine oil in my lawnmower?

Whilst some 4 stroke lawnmower engines can run on automotive oil, it's advisable to use oil specifically formulated for small engines. Garden machinery oils contain additives optimised for the higher operating temperatures and different load conditions of air-cooled engines. Always check your equipment manual first.

What's the difference between 25:1, 40:1, and 50:1 mixing ratios?

These ratios indicate how much petrol to mix with oil—50:1 means 50 parts petrol to 1 part oil. Modern equipment typically requires 50:1, whilst older machinery may specify 40:1 or 25:1. Using too much oil causes excessive smoke; too little risks engine damage. Always follow your manufacturer's specified ratio.

How often should I change oil in my 4 stroke lawnmower?

For domestic lawnmowers, annual oil changes at the start of the mowing season are typically sufficient. Professional users should change oil every 50 hours of operation. Always change oil whilst the engine is warm to ensure complete drainage, and dispose of used oil responsibly at your local recycling centre.
