Castrol POWER1 A747 1L

Product Information

Today’s cheap two-stroke oil is far better than the quality two-stroke oil of 30 years ago. Expensive two-stroke oil might be deemed unnecessary by some, mainly because vintage or classic motorcycles don’t rev to the same high rev ceilings as modern machines but if you can afford it, go for a quality brand like Castrol’s A747. All two-stroke oils create smoke and you have to remember that even the cleanest engine burn will emit some unburnt petrol and oil and some partially burnt, which is where the smoke comes from. When comparing a two-stroke engine to a four-stroke, the most obvious difference is that in a two-stroke engine there are two complete revolutions for every combustion cycle, whereas, in a four-stroke, there are – you guessed it – four! The semi-synthetic oils are a blend of conventional synthetic developments combined with natural oils of greater consistency. In general, the balance of these oils is a bulk of mineral with a small amount of synthetic additives. The oil blender also comes with a cross section of synthetic additives. Many of these have their own specific identity and purpose enabling a more accurate blend of oil to produce the performance and emission requirements accompanied by affordability for the modern 2-stroke high-performance engine. Castrol POWER1 A747 is a high performance part synthetic two-stroke lubricant. It is designed primarily for use in water-cooled motorcycle engines of very high specific power output, as well as high performance Go-Kart engines.

If your ratio is 25:1 that means 25 parts of petrol to every part of two-stroke oil. So for 1 litre of petrol you’ll add in 40ml of two-stroke oil. https://cdn.opieoils.co.uk/images/variants/icon/castrol/castrol-power1-a747-2t-semi-synthetic-2-stroke-racing-motorcycle-engine-oil-1-litre-2.jpg Captain Pugwash, I’ve heard about these problems quite a lot. I use Castrol R40 all the time and with regard to settling in the petrol tank I think there may be something in it. I rode my scooter (S2 TV175 engine) around this morning and there was frost on the grass and on windscreens. The old girl did seem to smoke a bit more than usual at first so perhaps the oil was starting to settle at the bottom of the tank. Time will tell on this score because I shall be riding her around whatever the weather.In the last 5 years or more, the new completely synthetic 2-stroke engine oil as it is widely called has come a long way. Newly engineered polymers, biodegradable inclusions, detergents and additives that have exceeded previous lubricating standards now have other recognisable characteristics, such as octane enhancement and stabilisation, gas generating compounds to further improve combustion providing almost smoke-free emissions. Quality burning and lubrication allows some production motorcycles to run 60:1 in fuel / oil ratios, even in high revving 60cc 2-stroke racing engines with long service intervals and no undue wear of internal engine parts. A Vespa, like any other 2t scooter, needs a quality oil. Any JASO rated oil will be ideal and yes, it’ll be a little bit more expensive than the cheapest stuff but it will ensure your engine runs well. Firstly, you should never run your motorcycle on two-stroke oil that’s designed for a hedge strimmer or a chainsaw. It just won’t be able to keep up and a few miles down the road, your bike will seize.

It is suitable for all makes of 4-stroke bikes, both carbureted and fuel injected where API SL (and below) and JASO MA or MA-2 specifications are recommended. I have run mine on R40 for years and I’ll leave it up to everyone else to decide what they think of my decision as I start to make my replies. I do think ratio is very important and I have tried 50:1; 40:1; 33:1 and 25:1. Recommended oils: Silkolene Scoot Sport 2 or Castrol Power 1 2T Scooter Best two-stroke oil for a trials bike It’s really good to know I’m not the only one using Castrol R! And really interesting to hear your replies, so I’ll try to answer as many (or perhaps the few) replies to this topic. This question is a little bit like the question of ‘what’s the best high street coffee chain?’. The answers are numerous, mainly based on opinion and can be debated until the cows come home. Then someone will come along and say none of them are any good and really throw a spanner in the works.

This shows that XR77 is more economical in terms of fuel consumption and a better choice comparatively. Summary
