HSM Posted August 11, 2021 Report Share Posted August 11, 2021 Just changed my spin on oil filter on the '6', I ordered a Man filter ( cost £3.95 ) and a Bosch ( cost £7.75 ), on comparison they were actually identical apart from the name on the filter body. The answer is £3.80. Work that one out Harvey Quote Link to post Share on other sites
RogerH Posted August 11, 2021 Report Share Posted August 11, 2021 It would be interesting to see the filter paper. Mann filters tend to be used in commercial/industrial applications so perhaps Bosch are using the public as a cash cow. Roger Quote Link to post Share on other sites

barkerwilliams Posted August 14, 2021 Report Share Posted August 14, 2021 (edited) Not the same but.... I used to live near a cucumber grower, he had two packaging lines, one for M&S and one for the rest of his customers. The M&S specification and inspections really did result in differing products, even from the same plant. So perhaps your oil filters have different specifications. Buy one of each and open them up. A worthwhile experiment for a tenner. Alan Edited August 14, 2021 by barkerwilliams Quote Link to post Share on other sites

Please do bore for England. Given your parameters, which ones for TR2-4A spin on conversion, available on the market, whether expressly for TRs or not, would you recommend?

Charlie D Posted August 28, 2021 Report Share Posted August 28, 2021 When I was at school a friend went to Rome for his holidays. He told me that outside the Vatican were stalls of people selling religious items (Tat). One man had two trays of crosses. One contained “Ordinary” crosses, the other contained exactly the same crosses, except these had been “Personally blessed by the Pope” and were 5 times the price of the “Ordinary” crosses. The blessed crosses were the most popular, and my friend noticed that every time the stock of “Blessed” crosses got low, the seller would wait until there was no one at his stall and then top up the “Blessed” stock from the tray of “Unblessed “ crosses. Maybe the expensive oil filters have been blessed by the Pope. Charlie Quote Link to post Share on other sites
