09 Lancer. No leaks but last change we did it burnt through a bit of oil (I think we used a low grade synthetic whoops). Which would be more appropriate? Cheers

Stick with a decent 10w 40

Pretty sure those are all running 4B1 series engines. They use a very thin full synthetic oil like 5w-20 usually. I most definitely wouldn't run 10w 40 in it.
How much did it burn and what engine exactly do you have?

Mitsubishi use 5W-30. Castrol recomend Edge 5W-30.

What grade did you use last time? What engine? What sort of distances did you do, Short/ long / combined

Like kaz said. stick with 10:40. if you use one a them 5 oils your going to burn heaps of it.

Thanks for the responses. Last change was 5-30 fully synthetic as per manufacturers instructions. Burnt quite a bit (had to top it up about 1L around a month before the change interval). We did a big trip of around 1200km in 2 days but aside from that it's just around town driving. Engine is a 2.0L 4B11 I believe.

1 litre top up in between changes is not too bad. You should really stick with what the manufacturer recommends.

This, exactly this! Just use the "product finder" for the brand of oil you wish to use and stick to that. It should be suggesting a thin full synthetic as above. Those are a modern and sophisticated engine design where the lubricant is working hydraulically as well as lubricating bearings. 10w-40 or 20w-50 mineral is going to be well out of the design spec and could well cause unintended consequences. I have run sophisticated engines on thing synthetics for years, that consumption is quite low and won't likely cause any issues running the correct grade/type.

Get a longer dipstick like what Holden did for the Colorado, then you will have plenty of oil between changes.

My only concern is the cleaning ability of the full synthetics, that and the fact that they're quite thin. I don't want to clean the engine so well that we end up with leaks!

I wouldn't be worried about the oil consumption at all, since some new cars are now using 0.5-1Litre of oil per 1000k in some cases and apparently that's acceptable.

Detergent levels are similar to mineral 10w-40 etc. It's old fashioned Diesel engine oil that has lots of detergent in it.

And what cars would that be. I don;t think I've come across anything new that uses oil. except for a Colorado that is.

Thanks! Will stick with the recommended oil.

1 grade version difference upwards shouldn't hurt. It's not a race engine under sever high rev & temp conditions. Try a 10/30 or a 5/40 of the same brand & see what happens. The 10/30 should tell you if it's using oil before the engine gets up to full temp (typical of town driving) & the 5/40 should do the same for full temp/ highway driving As engines get older/higher km's, they wear more & do tend to start burning a little more oil & at that stage, a thinner oil will get used faster then a slightly thicker oil
Full synthetic oils do tend to get consumed faster then other grades & maybe even a good semi synthetic of the OEM spec weights, might be the answer in your case
Been there many times with older vehicles were we have gone from factory recommended grade to a slightly thicker oil & consumption has slowed a little & gone the other way with a thinner oil & consumption has increased.

Just thinking about this-im sure Im teachin grandma how to suck eggs here but--I do wonder if you checked your oil level before a startup -when you did the change. Ie pre the filter filling with oil. on the oil front I would be comfortable going to 10w 40 for that engine PROVIDED its not sitting at below zero temperatures overnight on a regular basis.

Would a bad Crankcase ventilation valve cause excessive oil consumption? And (BMW's) I think I read somewhere that some BMW's, like late 90's, use huge amounts of oil & BMW say to use a 0/60 oil. True?

Yep blocked PCV valve could do that & force oil out places it shouldn't be

Was also wondering if excessive vacuum would pull oil into Intake.

I would be concerned that you're relying on dirt to stop your engine leaking oil.

you need the oil it needed from new just because it has miles on it dont means the specification or oil port sizes change magically.

i agree with that statment
