3.8 V6 Fuel Economy Improvements Bang for Buck

[VR 60]

Hi, do you think Morey's injector cleaner would affect the O2 sensor?

 

[losh1971]

I doubt it or it would have been pulled from the shelves because most cars on the road these days have an O2 sensor and people would be complaining no end.

Best to have some heat in the exhaust to get the oxy sensor out mate wear some gloves so you don’t burn your hands of course

Ditch the moreys will probably help your economy it thickens the oil and makes it too hard to pump through the engine it kills more engines than anything its 80 weight diff oil in a bottle lol does nothing but starve your bearings for oil and cause drag on the engine

I might have missed something but he mentioned Morey's injector cleaner not oil additive. If he meant that oil thickener **** then totally agree it's terrible stuff.

Well I have a 03 VY Ecotec,

Fitted 2 1/2 extractors to dual cats with a 2 1/4 twin system,
CAI,
12mm plenum spacer,
69mm throttle body,
Retuned ECU from mace,
NGK leads and iridium plugs.

On the highway average use is 7.6l/100kms
On 60km around town it's 7.6-8l/100kms.

But the funny this is recently I got a vaccum leak, the hose between the pcv valve and throttle body come off,
Was idling like ****, but surprisingly was using a lot less fuel according to the computer,
On 60kms was only using 5.6l/100km

Running lean. Not a good long term solution to engine health.

Yeah it's back to normalise now using more then before, feels like it's lost a little torque, still getting p705 fault from a vaccum leak though will have to look around for more after Crissy
