How many km has your car done? I changed the fluid in mine at 100k and it was obviously tired and looked much darker than the new replacement fluid.
Be very careful to use the correct fluid if you go down that path. I am in Oz and we have a Penrite replacement here specifically marked as suitable for MGF and it has worked for me. It is not a big job to do
Hello Frank,Hi Harry
Sorry for the delay in replying. Here in Great Britain we still use miles - 1750 yards to the mile, 3 feet to the yard, 12 inches to the foot - I'm sometimes amazed that we ever stopped buying things with Groats but I'm sure that there will be some flag waving Little Englander out there hassling to get them back! To answer your question my F has done 71,000 miles which is over 100,00k. However, I changed the fluid and filter recently which made a significant difference at the time. As a matter of interest, when I bought the car as a 'project' 8 years ago I noticed that the fluid was black and smelly so I replaced it then - with ATF! It ran o.k. and it wasn't until I read last year that this was a heinous action with dire consequences that I decided to change it again. I would point out that this car is a summer only toy which only covers a couple of thousand miles a year. The 12 volt diesel/oil pump from LIDL (only £13) makes getting the fluid down the filler tube a doddle. Getting the sump off requires a selection of spanners and, preferably, the assistance of a triple jointed gnome. Torque it back up to the correct reading? No chance? Tighten and pray.
