Temp gauge also acting funny ?

Could this be a Head Gasket issue?

I'd take it to a garage, get it checked out.

I take it you've done the obvious stuff, like inspecting the air filter + inlets?

172's are incredibly thirsty for a 2 litre coke can, but you should be able to get at least 27mpg urban, and at least 35 on a run. Any less, it's wallet clobbering time. Have you got a local friendly garage with a Snap-On diagnostic box?

Do you have mayonaise like stuf under the filler cap? Its very unlikly to be head gasget there very strong realy.

Most likly as said the coolent temp sensot has failed or the wires are sligtly stretch/earthing.

its not the headgasket as ive had that checked! its startin 2 go abit better now 2 b honest in my veiw i think the cat might b on its way out

The Cat? Hmmm, how many miles has she done? If you suspect exhaust, it could be the baffles in the tail box collapsing then clogging.

Maybe mine's fooked too then! I drive her pretty gently most of the time. I'm going on a 4 hour motorway run on Fri, I'll reset the trip and see what I get @ 70.

Sorry for hi jacking, but does everyone else's full fat return 37 mpg urban? Thought mine was a healthy example. I don't run with the air-con on, apart from the occasional burst to clear the windscreen.

 

[kully]

good driving would defo be involved in that kind of return , 28-33 about normal imo

 

[stewart reeves]

I get 34 in mixed everyday driving, 28 when I thrash it. But -6mpg = many more smiles!
