1.4 almera MPG

Peterbilt

What would cause high-ish MPG in an Almera 1.4? Air filter new. Brakes not binding. Would blocked CAT or dirty MAF sensor be the culprit?

When was it last services (oil, filters)? And what kind of MPG do you get. Mentioning the type of driving you do would help also.

Serviced only 2 months ago. 63K miles. Mixed driving I get 29-30mpg. My 3.0 diesel Trooper does that! It's not smokey. Idles at around 800rpm but often lingers at around 1500rpm before going down to 800. Was expecting 36-38mpg. Dont know anyone who has the older 1.4 to compare with.

I was getting 7-8 lt/100 km of fuel consumption from a 99 1.4 almera. it was around 70k miles and serviced on time.

Your consumption seems high unless you are doing short distance stop-start driving with a cold engine.

Peterbilt

Whats that in mpg?

CianRyan

About 35 which is bang on, I think I get about 30mpg from mine but I have a fairly heavy right foot.
Not an economical car at all, it'll make it easier when I'm getting around to 20mpg on my future cars though. :pac:

Around 38mpg convertor says. Mines a guzzler in comparison.

I didn't push car too much but 30 mpg still seems high to me.

It was always lower than 8 lt/100 km for me unless I hit traffic but I never saw less than 7lt/100 km regardless how long or careful I drive. It wasn't most economical 1.4 lt engine out there but it was bulletproof.

A service with air filter and spark plugs changed would be a good start. Check if tyre pressures are normal.

If you are doing very short runs with cold engine in winter time, it may be normal even.

I spend half of my time in traffic and the other half accelerating to 80kph so that'd explain the bad econemy.
Very strong engine alright, pokey enough too for what it is.

Peterbilt

It's fully serviced. Tyre pressure fine. 29-30mpg for mix of motorway/town for 1.4 cant be right.

CianRyan

It is though, it's a thirsty engine.

Peterbilt

Thanks for that everyone. Only got it recently. They do have excellent reputation and am overall happy with it. Just thought it would be better on juice. Parkers Guide say 42mpg!

CianRyan

42? Maybe for a Peterbilt but not for a petrol Nissan hatchback.

Peterbilt

Cant see any peterbilt doing 42 either! Diesels have me spoiled.

What speed are you doing on the motorway? If you are travelling at 120kph the car will be drinking it as it has to work harder. I'd look at modifying your driving style as 30mpg wouldn't be too bad if you had a heavy right foot.

Have you had the fuel filter changed? The fuel filter on that generation of Nissan is a standard service item, due every second service but in most cases in Ireland its never changed.

Its always the first thing I look at on any 90's/00's Nissan that comes in complaining of poor MPG and in most cases they are still the original filter.

kerten

I have changed fuel filter of that Almera just after buying it. It may be the reason of better mpg than others as he suggests.

CianRyan

Must look into that, where's the fuel filter located?
Front garden job?

Its on the bulkhead at the rear of the engine, opposite the master cylinder.

A smallish Gold or silver coloured cylinder with a pipe into either end.

Cheap to buy and easy enough to change although, as most have been left so long, it can be a pig to get the pipes off it.

CianRyan

Should be able to get the part cheap so I'll have to give this a go.
I seriously have to get a Haynes manual.

Peterbilt

New fuel filter for me too. Thanks lads.
