It apears that the Fleetgaurd has more pleated media so better filtration?
All I know is that I wont be touching a Fram product again. I changed the oil & filter on my 1990 Range Rover Vogue 3.9L V8 and it took 10 seconds for the oil light to go out on a cold start. I replaced the oil filter with a Mahle brand filter from my local Land Rover specialist and the oil light goes out immediatly.
Supercheap Autos im my area has ceased selling Fram products and now sell the Ryco range.
