        The cheap steel jerry cans work well if you want to keep it for some reason.

        But anything will last the hour or so it takes to drop the old oil off at the local SCA

    I have a car that needs 4L and just keep the extra 1L in the same bottle for top ups if required. The next time I do an oil change, I use the 1L (or whatever is remaining) first before the next bottle (assuming I am using the same brand and spec of oil that is).

    Open oil should still last 2 years or so if kept in reasonable storage conditions.

      For dealing with old oil, I ended up getting a ~10L large plastic oil container from Supercheap which has a screw on top.
      I do decant that into milk bottles or drink bottles which I take to my local recycling centre (which they do accept).

      Supercheap do have oil recycling also though I think they will only take it in proper oil containers.

  • 

    Matt86 on 23/08/2023 - 20:16

    Legitimate answer here - get a small container and store it, like a thoroughly washed Pepsi, Coke, etc bottle. Put the used oil in this.

    I'd encourage to put a plastic bag or similar over the top and rubber band around the lid to prevent leakage as we know oil will penetrate.

  Is it compared to the likes of Castrol Edge? or Penrites HPR oils?

    Castrol Edge is API SL 2001

    So looks like better grade

      Only reason for the SL rating on Castrol edge is due to it exceeding certain additive limits that an SM or SN rating imposes.

      It would be a better performer than the Gulf Western.

        You seem to know a bit.

        I have a R36 Passat that calls for "VW 507.00" Which basically severely limits options. However I understand that they're all "long life" oils. (E.G Castrol Edge 5w-30 LL) - I do yearly/10k services - would it really hurt to go with the regular Castrol Edge or even this which is 505.00 approved?

          @Matt86: It's sound logic and I've often thought the same, but hard to know for sure and with a Euro engine I'd be a little wary of deviating from the spec.

          FYI Edge LL is on sale for $69 at Repco at the moment. I'd pay the extra for the peace of mind.

          I have a R36 Passat that calls for "VW 507.00"

          VW 507.00 is a diesel spec. You have a petrol engine.

          Your R36 Passat will ideally use a VW 504.00 spec oil which is for the Long Life variable service regime which we don't use in Australia. Availability of 504.00 oils was an issue 13 years ago when it was $90/5L but there are plenty of reasonably priced options now.

          VW 502.00 is the recommended spec for the 15k km /12m service interval that VW recommends but if you love your vehicle you'll drop back to 10k km intervals. There are dozens of 502.00 oils available in 10w-30 and 10w-40.

            @brad1-8tsi: Have been doing 10k for a long time, 5k on my Audi.

            R36 is meant to be 18k which is a joke, almost every R36 owner does 10k to try and prolong the life of the dreaded chains (the actual issue is the guides).

            My understanding is the OEM is Castrol Edge 5w-30 LL - that's what the Castrol website recommends but 504.00 is considered fine after reading. Penrite also suggest a 504.00/507.00 approved oil.

            I think I might swap to a 504.00 after I get one last tin of Edge since I have around half a container left. That way I can do one more service on it and have minimal waste.

            Thanks for the advice.

              @Matt86: Mate. You slightly misunderstand some things. I'm a bit of a specialist on VW stuff.

              In Australia R36, and all other VAG product from around 2000 onward were 15,000km/12 months service intervals with a minimum oils specification of 502.00/505.00. The former being the petrol spec and the latter the diesel spec. The oil was the same.

              European/UK markets had the "Variable Oil Change" interval when fitted with the sensor in the oil pan. This required the 504.00/507.00 spec oil. The former being the petrol spec and the latter the diesel spec. The oil was the same.
              Depending on model and engine variants, variable service intervals of up to 2 years or max. 30,000 km are possible for petrol engines and 50,000 km for certain diesel engines. This is nuts if you want your car to last beyond VWs expected lifespan (about 8 years).

              Castrol Edge 5w-30 LL is VW 504.00/507.00 approved and always has been.

        Rubbish! Its a SL rated oil because it has not passed the tests to be a SN grade oil, its a quite poor oil rating wise compared to an SN oil. API ratings are earned by demonstrated performance meeting a standard.

        This is basic stuff.

          @ghosta: Not so, the API has limits on additives for certain oil grades. From Penrite website:

          When API SM was introduced - for the first time, the limit on Phosphorus was from 0.06-0.08% (600-800ppm). There were industry concerns about the applicability of these oils in older engines. However, the limit only applies to 0W-20, 0W-30, 5W-20, 5W-30 and 10W-30 oils (so called “ILSAC” grades). Any other grades were exempt from this. When HPR 10, 15 and 30 initially went to API SM technology, they maintained their Phosphorus levels of approximately 1000ppm (about 1100ppm zinc). None of the viscosity grades for these products are bound by the 800ppm upper limit.

          The other approvals that the Edge 5w30 has such as LL01, 229.5 etc are far more stringent than any of the API specs. Suggesting that it's not good enough to meet SM but able to meet 229.5 is laughable.

    An often debated topic. This will be a Group III base oil. That would be the same for Castrol Edge and Penrite's synthetic oils to as I understand it. The only oils that move into Group IV base would be top of the line, and top dollar racing oils (maybe Shell is still Group IV for their oil derived from natural gas?).

    Regardless, my method is to use whichever "fully synthetic" oil is on sale and do my oil changes at 7500km or 6 months, which ever comes first. My last change in both cars was Nulon, and I have stocked up on some Gulf Western for the next changes.

        ghosta on 23/08/2023 - 19:29

        I was like you and changed my oils at 5k or 6 months, Then when I read up on oils at the website bobistheoilguy and other sites I realised how much money and time I could save by switching to full synthetic oil and doubling the oil change interval to 10-12k or 12 months.

        Since then, prices for synthetic oils on sale are similar to sale prices to straight mineral oils, semi synthetics can be even cheaper!

        Oils have improved enormously, and unless your engine is constantly stressed through racing or towing under extreme conditions then to change oils at anything less than 10k is not smart. But it does take a change of mindset!

    What the hell? Crush washers - yes but sump bolt? Are you rounding the head / destroying the hex socket every time you remove them?

    I've done 26 oil changes on my current car and it's still the factory issued bolt. I change the sump plug washer every change but only because they cost bugger all. If you don't over torque the sump bolt it's next to impossible to destroy it.

    Also, which euro exotic are you driving that requires two or more sump bolts?

  • 

    Matt86 on 23/08/2023 - 20:22

    The even better option is to learn to do the basics yourself if you can! The tools to do spark plugs would cost you around $20 at most (if you have a 1/2 inch drive already) and you've then got the tool for next time.

    I'm surprised dealers even use your own parts, I've not really dealt with them much but my experience is that they won't touch anything you provide and push the "genuine parts" rant down your throat.

        I'm going to add some more info on this one. While a small top up with a different brand of oil with the same viscosity and specification is likely not an issue, mixing a large percentage of oil in your engine might be.

        Manufacturers produce a number of different variations of oil products for the same viscosity. These oils have different additive packages and meet different specifications. What we don't know is how the additive package of oil A will work with the additive package of oil B. Are they compatible, are they not? It is unknown and certainly untested.

        This article explains it well: https://www.machinerylubrication.com/Read/235/mixing-lubrica…

    Oil extractors are convenient but the issue is that they can leave the rubbish at the bottom. It is (in my experience) better to let it drain out if it does have a plug as it will push all of the rubbish out of the bottom.

    It will depend on how old your car is and the general engine wear it is having however.

    Cars without dipsticks or sump plugs are just plain stupid though.

  Looks like decent price, before placing the order, I tried to find the HTHS specs of the oil, can't find it in the specs sheet…

  • 

    Skips on 23/08/2023 - 11:50

    Castrol Edge 5w40 is at least 3.5, as this is a requirement of the approvals that it carries (such as A3/B4).

    While the specs of the Gulf Western aren't published the same logic could be applied here, assuming they have met the approval specs that they claim.

    • 

      terrywang on 23/08/2023 - 22:56

      You are right, there is a minimum standard.

      Contact sales and got the following response.

      "Any time you have either of the following specifications: ACEA C3 or ACEA A3/B4 you are guaranteed a minimum 3.5cP HTHS.

      By the way, unless you have a diesel engine with diesel particulate filter (DPF), you may also want to consider our Syn-X 5000 5W-40 which has the ACEA A3/B4 specification and has a HTHS value of 3.7 cP."

            From the car manufacturer's view, as long as the oil meets or exceeds the specification(s) they list, then you are fine to use it.

            If you want to be certain, I'd suggest contacting Gulf Western's support line. I've called both Nulon and Penrite support in the past and both were very helpful in checking compatibility and answering questions about their products. I suspect Gulf Western are the same.
