Hmmm, my mechanic at my last service told me my "new" car should only have synthetic oil used. It is an automatic, is this the norm for auto's? Car is a 2008 Toyota Avensis 2.0l

It doesnt matter whether is auto or manual, it will use the same oil.

Any car from 2005- can use Castrol EDGE (fully synthetic)

Ockie, phone the place that services the car and ask them what oil they use. If it's not a dealership phone your local dealers service dept and ask them as well.

Dont stress about 1 pint of oil not being the same, it wont harm anything. Just drive the damn thing till it needs a full oil change.

so a question, any idea why the car is taking oil? seems like a new car.. anything more than a top up should not be required.

New cars will use oil until properly bedded in - up to 1 litre/1000 km is considered acceptable.

Also a MAJOR warning - to not get the guy at the petrol station to check your oil. A car needs anything up to 15 minutes ( more in a Subaru) to give you a correct oil reading. Bottom end is that 90% of the people who add oil because the petrol attendant told them to, are actually over filling their engines and that can be harmful.

I swear by one oil
Mobil 1 0w40.
Engine looks spotless inside, oil never needs topping up.

We all get stuck up on what oil to use, normally going for the premium oils, only to find the stealerships using real cheap part synthetic

And then charge you the price of halve litre cans as used on drive ways while they keep it in 220 litre drums which is much cheaper from the whole sale oil suppliers.

Mobil 1 is excellent, but also R200 a litre.
Castrol edge professional is also great, but expensive.

Castrol edge sport is a low quality synthetic oil.

There are way better synthetic oils out there in the same price range, eg Ravenol

You should use the best you can afford.
I would rather use a better same price semi synthetic

Faz, I don't agree with you wrt the first part. A new car should not be using oil, except if it's a VAG direct injection.

Second point - I couldn't agree more. Always check what oil spec your engine uses and buy a 500ml bottle from your dealer/Midas and keep it in the boot for emergencies.

Castrol is better at marketing that oils, rather get something decent like Shell Helix or Mobil or Fuchs or LiquiMoly or Motul.


To answer the OP: I would not mix oils, esp different grades or synthetic/mineral/part synth.

Well, I checked my oil and it was low. Was just touching the minimum mark on the dip stick. Bought two 500ml bottles of Castrol EDGE @ Game and ended up putting one bottle in. Was careful to put some in, and then check the level, and repeat. Wanted to make sure I dont make it too full (though on the net some say that there is a bit of a safety margin even after the max line). Ended up taking the 500ml bottle completely and is now just a little bit over the halfway mark between the min and max level indicators.

When car goes for its oil service in about 8000km I will buy a can of Castrol EDGE and tell him to put that in. Dont want some no name brand part synthetic oil in there that he has lying around his shop.

eish Ockie, surely you can afford something better than that Castrol p.o.s? :whistling:

first thing I did when my landy was out of warranty is to get rid of the Castrol and switch to a proper full synth. Straight away engine ran more smoothly and a couple of degrees cooler.

Recommendations: Shell Helix, Fuchs, Mobil 1, Liqui-Moly.

Urg. But on the engine it itself it says Castrol recommended? Googled Liqui-Moly now. Where do you get this? Is it much more expensive than Castrol EDGE?

Castrol EDGE is fully synthetic though?

Naks you can contact any manufacturer you like and they will give you the same answer as I did - up to 1 litre/1000 is acceptable on a new engine.

That will be fine Ockie - leave it like that, but keep an eye on it - it should stay stable now. Castrol Edge is just fine - there are no "rubbish" oils out there today, particularly on the synthetic side.

Yes it is FINE!! Check my answer above. Don't let these people hassle you with their own favourites!

Liqui Moly is German and very expensive - total overkill for your car.

I googled oil usage for my car and it seems it is normal for the car to use some oil, specially in stop go conditions. It has been a good few months since the last top up so it uses it slowly, which seems normal.

He is 100% right that a brand new car (as in <50km on the clock) will burn some oil.

However it's not nearly enough that it would actually require topping up before hitting it's first service.

In fact I would say no NA cars under 120 000km or so should require any topping up of oil between services. Yes they will burn oil and the dipstick will go down but they will never run dry.

If they do, then something is wrong.

Turbo cars on the other hand do turn to burn a bit of oil and you need to keep an eye on that oil level, but again probably only really need to make a special effort ever 5000km.
