Hi all, I have a 3.4v6 and doing a fair bit of mileage the last few weeks. I have been getting 10.5-11 Litre to 100k. Anyway she's still on stock springs and shocks with 200k on it. I want to change them for a lift 2inch and been looking at Dobinson. Will this affect fuel economy much?

Also how much oil do you put in after an oil change with a filter and what do you guys use?

Thanks all for the help.

The lift might increase fuel use marginally. Really not much.
Some bullbars change the drive a lot & increase fuel use by around 1 lt/100k.

Put oil in until the dipstick is at the full line on the dipstick is the best way to go about it.
Re-check after running the engine. Let it settle for 2 minutes. Check it on flat ground.
Penrite oils will keep you out of trouble, Aussie oil, plenty of grades to choose from.

I know someone, they can help you with Dobinsons suspension......p.m me if you like.

if you have your owners manual it does specify the amount of oil you need to fill with and without filter. Its in the back of the manual where you have the gas tank capacity and such info. You also have differential oil capacities, transfer case oil capacity and transmission oil capacity specified.

With my lift and increased tyre size and a lot of extra weight I get 15L/100. Best I got before adding all the extras was 12.5
