Octavia MK3 oil top up, which brand?

[sillyboy]

Hi,

I had the 'check oil level' light on the way to work this morning, haven't check it yet, but I am assuming it needs a top up(car only done 3800kms though).

I am wondering if anybody knows what brand of oil is it in the Octavia RS MK3(the oil from the factory)?

Otherwise does it matter if different brands of oil in the car?

Thank you.

As long as you stick with VW504/507 approved oil, it should be ok. I believe Castrol is the factory fill. My car seems to be needing a top up every 7000km or so, I used Shell Helix Ultra 5W-30 as it's readily available in the servo.

The service adviser from the dealership said it is Castrol 5w-30 full synthetic, he said I can pop up and they will top it up for me ( free of charge I am assuming?),
I guess I will just go there this afternoon.

That's another option and yes it should be free of charge.

Thank you Reza, I might keep a bottle of oil in the boot next time I go for a long trip, just in case.

The brand doesn't matter as long as it is certified to the specification. Shell, Castrol, Penrite, Liqui-Moly, Fuchs, Mobil1 are all VW certified (and there are others). Nulon are tight and have the numbers 504.00/507.00 on the bottle but haven't paid VW for the testing / certificate so I would avoid them.

If it's a diesel it has to be 507.00 because of the DPF.

If it's a petrol then you can use either 502.00 or 504.00 without issue. 504.00 is the better spec though.

Having the oil light come on at 3800km is disconcerting but it's a new engine and will hopefully seal up with use.

Have you checked the oil since you took delivery of the vehicle? Maybe it was low from day 1? The owners manual says to check the level every fuel fill. Given you know it uses about 1L/4000km I'd be inclined to check the level every 1500 - 2000km and not let it go below the low mark on the cross-hatch. When the light comes on it's right at the limit IMO.

I must say I am not a very handy man around the engine bay, and I was lazy, so I did not check the oil level, I will start to do so after this top up.

Is it true that the differences between the highest and the lowest reading of the dipstick is only 0.5L? I read this in some other forum(Briskoda I think)

Have you checked your tyre pressures since purchase?

500ml from the bottom mark to the top mark sounds about right. Maybe a fraction more but I've never paid much notice.

^ i believe its closer to 1L on my Golf from the bottom of the hash mark on the dipstick to the full mark. But too be honest, i don't pay too much attention - i just pour slowly and check it a few times until its right on full.

Shell Helix Ultra EXTRA is the 504/507 VW approved oil suitable for both petrol and is the grade that must be used in diesels and is not normally at servos or even Supercheap etc Helix Ultra is a 502/505 grade for petrol engines

Ya, I check every 3-4 weeks, amazed me when I see one of those guys who pump their tires from 12 PSI all the way to 36 PSI(and I had to wait for 10+ mins for him to pump the tires up), I guess I am like one of those guys to you people's eyes, except it is for the engine oil in my case.

So, I planned to visit the dealer, but Sydney north's traffic on a Friday avo is unbelievable ,so I ended up buying a 5L bottle of Castrol Edge 5W-30 VW 504 from Repco, they only have couple brands with that spec, so I picked the Castrol as it was the oil in the car.

Open the bonnet and check dipstick ,it was down to about 3mm below the minimum mark on the dipstick,Topped up the car to about 65% of min to max, didn't want to overfill. and it was fine, the warning sign gone.

Thank you Guys.

I checked regularly and even noted consumption in my service book. It used about half a litre during the break-in period. I reached the bottom line at about 7000kms, put a litre of the Penrite stuff in (to the top line) and it doesn't seem to have used any significant amount since. We're now at 14,000.

Yup that's the one, checked the bottle, Extra ECT or something. Quite expensive too, 20 bucks for the 1L top up. My local Shell seems to carry them all the time.

I usually almost have to use the whole 1L bottle whenever the dipstick indicator is at the minimum level.

Just check on the label that is says APPROVED for use with VW and the rating as some are rated 502/505 which is NOT for diesels.

I cant find an extra ECT in the list of approved oils in either rating.

Very few places carry the 504/507 and usual best avialable is the Penrite Enviro+ 5w 30 at Autobarn or Supercheap
