Oil change is easy enough to do. Get yourself a new oil filter and the oil of your choice (i use magnatec GTX). If you look under the car, on the bottom of the engine you'll see the sump. In the middle of that (facing toward the back of the car if i remember correctly) you'll see a stubbt bolt. You'll need an alun key to remove this. I can't remember the size of it, but its big!
Warm the car up, and then leave it stand for a while (so all the oil collects in the sump). Then just stick something to collect the oil under the sump, and preferably some cardboard under that as oil destroys tarmac. Loosen the sump plug, but don't remove it totally as it'll spray oil everywhere!
Once its finished dripping, unscrew the old oil filter (its on the front of the engine, below the exhaust manifold) and spin the new one on. Don't tigthen it too much. Some people say smear a bit of oil onto the seal on the new filter to help it seal.. i forgot to do that on mine! Then just tightn up the sump plug, and refil the engine with oil.
Fiat recommends 3,75 lt 10/40 whith filter
4 litres
The engine oil capacity of a 2003 Fiat Sciecento is approximately 4 quarts. The recommended oil is 5 W 30.
The engine oil to use depends on the type of engine (diesel or petrol). See the car manual to know the exact oil reccomended by FIAT for your car
FIAT 500 and Dodge Grand Caravan: To reset the 'Change Engine Oil' indicator after an oil change: Turn the ignition key to "on" without starting the engine. Depress the accelerator pedal fully 3 times within 10 seconds. Turn the ignition key "off". BTW: It's on page 143 of the owner's manual.
It's depends on the engine size!!
Most cars are equipped to reset oil change warning lights. If the Fiat Doblo does not have instructions in its manual, then you will have to have the dealer or a mechanic do it for you.
Based on the 1.2 engine the Fiat Brava & Bravo hold 2.8 litre of oil (remember to fill the oil filter first if your changing both oil and filter
3.8 litres
This job has to be done by a FIAT dealer
