        MI used to get called a skinflint, because I used to buy the cheapest possible vegetable oil – rapeseed oil. It was very often sold as generic 'vegetable oil' because of the negative connotations.

        But I had spotted it was lower in cholesterol and higher in polyunsaturates than sunflower oil, corn oil and even olive oil. But where was the premium market for a British product instead of these exotic oils?

        Today in Morrisons the cheapest oil is sunflower oil! Even the generic vegetable oil next to it is sunflower oil with a different label on!

        You can't buy own-brand rapeseed oil anymore, I had to pay a 30p premium to get a bottle of it. I'm sure rapeseed oil is cheaper to source than sunflower oil,looking at eh bright yellow countryside!

        Call it 'canola' or 'cold pressed rapeseed oil' and the prices are getting into olive oil territory.

        Amazing how the premium and cheap and cheerful products have exchanged places!

        I wonder which is best for oil blacking?

          Rapeseed oil is still sold as an inexpensive vegetable oil by other supermarkets in UK.

          I know this because I had to buy some last week. I mix it with 460 grade Steam Cylinder Oil for use as a general lubricant on my little steam engines. smiley

            Years ago I used to buy cheap cooking oil to run my Discovery, it was cheaper than diesel. I never did run totally on veg oil though always adding around 25% proper diesel.

              Rapeseed oil has been my oil of choice for blacking for a long time and works very well. I have kept the same tub of oil for years and it still works fine. I'm sure it must be 10 years past its use by date but the metal doesn't seem to mind.

                try buying Castor Oil. Last time I bought 4 small bottles from Boots. Brought a smile to the lady pharmacist until I explained that I needed it for my (2CV car) suspension.

                  During WW1 aircraft engines were lubricated with Castor oil, they had a total loss lubrication system which meant that a large amount of used oil was blown into the pilots face. Explains the choice of brown corduroy trousers.

                      A friend of mine use to add a little Castrol R to the petrol tank of his lawnmower as it reminded him of various motorcycle events.

                          In the 1970s, oilseed rape was barely known in Britain. Many people were suspicious of this alien seed which announces itself with its all-pervasive perfume, reminiscent of honey to some, cloyingly sweet and as sickly as regurgitated baby milk to others. Now it is our third largest arable crop. The Department for the Environment, Food and Rural Affairs (Defra) says that in the past year alone production has gone up by an impressive 17%. Next year, it is tipped to top 2m tonnes. In terms of acreage, oilseed rape now accounts for 11% of the crops cultivated in the UK.

                              Hi guys, back in my motorcycling days a friend had an Ariel Arrow & wished it to exude the fragrance of Castrol R, knowing how lethal it would be in a two stroke engine & the clean up problems it caused on our model aircraft engines (biological washing powder, magic), my solution was to secure a small cylindrical screw top container with perforated lid to a convenient bracket midway between the rear of the two cylinders, add a couple of teaspoons of R & Bobs your uncle (or mad scientist), fellow motorcyclists were having orgasms likening it riding round Brands Hatch, they never did find out how we did it, happy times.

                                May have been once well known, locally at least. The deeds for a windmill erected at Devices, Wiltshire, in the eighteenth century showed that it was built for processing rape seed. The Wiltshire county archives were rather proud to have discovered that.

                                I rather like fields of rape.

                                    Sadly it is not a forage for bees, unless it is spun out of the comb within 3 days it sets harder than Blackpool rock and has to be melted out and when put in jars will soon harden again. Taste is reminiscent of icing sugar and personally I do not want it. The bees , if having collected it cannot use it over the winter as it is too hard for them to break down for food. There are several types of flower that cause honey to crystalise like Red Hot poker and most Thistles.

                                    I have only once placed bees on OSR, never again.

                                    Lately I have noticed that the OSR is growing shorter, and that insects are not working on it, this no doubt because it is sown with Herbicide and Insecticide on the seeds. Contrary to the makers statement that the stuff breaks down on contact in soil it has been found to be still active 24 months later. Traces of both have been found in pollen again contrary to the makers statement.

                                      The oil bottle I bought yesterday shows a country spire rising in a boundless yellow landscape… to a younger generation (<50) yellow is the colour of spring fields!

                                      No doubt Clive will confirm it spoils the taste of honey and causes it to crystallise.

                                      Even so it was grown in Northumberland in the 17th century. It was an essential oil for steam engine lubrication by the nineteenth, and in WW2 there was a critical shortage facing the allies which led to Canada massively increasing production. I can't find any figures for UK production before 1969 (a mere 9,000 tons), but it does seem it wasn't totally unknown.

                                            Most "cress" sold in the supermarkets seems to be actually something like 95% rape these days. I suppose you could probably use almost any brassica for this purpose if you consume them before they have grown more than the initial pair of cotyledon leaves – cabbage, turnip, sprouts, mustard, kale, broccoli, cauliflower etc. And all have the same yellow flowers and cabbage patch whiff….

                                              My understanding was that Castrol R was a vegetable oil mixture, containing Rape oil, (will not mix satisfactorily with mineral oils) because of its extreme pressure capabilities. The smell in the exhaust was a bit of an acquired taste, but once hooked one became an addict!

                                              The fluid used in the suspension and hydraulic systems of the original Citroen DS was vegetable oil. The genuine fluid was costly, so a trip to the supermarket reduced the cost of top ups.

                                                Sainsbury's generic vegetable oil is now 100% rapeseed but it comes in a crappy bottle that dribbles all over the cupboard so for domestic use we buy Mazola (where did they get that name from? wink) 100% rapeseed oil in a nice container.

                                                Historically, I think rapeseed oil has only been grown for human consumption since the Canadians developed a strain that was low in erucic acid (Canola).

                                                  I buy Corn Oil because I like the taste, and because it doesn't harden to a laquer on the pans.
