Comedians- step back into your boxes straightaway, this info purports to be helpful!,and is not asking a question! fowlers in bristol have 4 litres of putaline fully synthetic 4t 10/40 oil for £26, reduced from £52 ( according to the label). there weren't many 'tins' left when I went through this eve. hope this is helpful for anyone looking for oil( and I don't mean drilling for it......) cheers tt
