I usually change the oil in my car every 10000 miles, but just read this article where it recommends 5000 miles, just interested in the thoughts of others on the forum.

Money wasted if you are doing 10,000 miles a year or more. Of just road driving. 

If you are using Long Life oil and changing it on Fixed Servicing that is good enough for a keeper.

Or maybe do not use Long Life just VW502 00 so 5w 40 FS for your fixed service regime Oil & Filter changes.

The fatness of their wallets is directly proportional to the number of oil changes they get you to pay for.

As said it does depend on what type of mileage the 5 or 10k-miles are, if they include lots of very short journeys then there will be relatively more wear on the engine and for the sake of a better word wear on the oil.  With very short journeys the oil may not get up to a a good operating temperature or for long enough with the oil not flowing and protecting as well and perhaps not clearing any moisture fully.

 

Have a look at the oil temperature on your gauge, on my wife's 2015 1.2 TSI (90) Fabia it shows a two line dashes until 50c, the book has normal range 80c-110c and not to push or strain the car outside of that range.

 

What is important to oil changes is the thoroughness of the change and the quality of the oil to the vehicle's use and way it's driven.  Quick cold oil changes will probably leave in the engine a greater amount of used oil and its containments as residue which means there will be less fresh new going in so the effects of the oil change are more diluted.  A hot longer drain will probably get more existing engine oil and its containments out meaning less residue so more fresh new oil goes in.

 

Modern oils of the correct type for the vehicles are fairly equal but some are more equal than others many engineers and mechanics will say to put in whatever you can get cheap and not to change too often.  Personally the way I expect my car to perform and having had many experiences of component and systems failures and breakages I prefer the additional wider protection of a better oil and thorough oil changes.

 

To really know when it's best to change the oil, and potentially engine condition, you'd analysis the oil, you can get kits or some garages may have and used them, serious stuff would be sent off to a lab but probably not necessary or cost effective for ordinary road cars.

 

ETA: I've already changed the oil on my wife's 2015 Fabia gearbox oil and am about to change the oil in the rear axle of my car, the mere thought of either would give many engineers and mechanics the vapours.  🤣

missing word

An old friend on the forum had his oil tested on his 1.4 TSI Twincharger.

 

When i test ones that have borewash and the issue was not the Super Unleaded but super unleaded & Long Life crap oil and a fundamental design and manufacturing failures,

i took out the dipstick and put a flame to the oil and watched how easy it ignited.  That was the petrol in the oil.

When I read that linked thread I'm sure(?)  it had that even a tiny amount of petrol would ignite the oil?

Well I find it strange/unusual/different that VW insist on their number specification VW 50* *** and not give a viscosity and have this different oils for different services which does make sense but confuses a lot of their customers but the German engineers work their way to get the fabled (in perhaps both senses of the word) engineering quality.

 

Large vehicle manufacturers having a commercial relationship with oil companies or blenders doesn't mean the oil they use or recommend is necessarily the best or most cost effective for consumers (and I don't mean cheapest to buy is best).

 

Most car owners, and many engineers and mechanics, couldn't care less about which oil and to some extent with a match of a modern car to the appropriate spec of modern oil I think it falls into belief more than facts, such as they might be.

 

 

 

@nta16

The difference is when someone tells you there engine has been producing oil you do clearly smell the petrol and when you take out the dipstick you do not need the match held that near to the oil.

When you have just oil and maybe oil and some contamination the match needs to be nearer.

 

The issue was VW Engineering. They just never admitted an issue, or issues.     So much more reliable without Long Life oil, still with Super Unleaded but better spark plugs than were OEM.

You'll make yourself as unpopular me if you carry on criticizing VW and any of their products and besmirching any German engineering quality and not wearing your rose-tinted glasses.  😄

 

I've always over serviced my diesel vehicles, especially if they are worked hard. Petrol cars I tend to stick to the service schedule unless it does a lot of short trips, then its worth shortening the oil/filter schedule a little.

I'm lucky as I get good rates on the parts and do the work myself, otherwise it wouldn't be viable. My TDI VRS is roughly £25-30 for an oil & filter change, so I don't mind doing it every 6k if it needs it.

What do you do for service history?  Just keep the receipts to show what you bought?  Do you think people will get funny about not seeing garage history when you say you've done it yourself? 

 

Asking as I've started doing my wife's car myself and wondering what impact would be on resale etc

Invoices and paper records mean lots more to many buying a used car than Main Dealer Servicing that is no longer in a service book unless you get one and just invoices and receipts if you get that.

 

Full Main Dealer Service History can be a history of not very much being done and maybe not very often. 

 

The impact on resale according to Dealers is huge, and when they sell you a car without a proper service history as you get even with Skoda approved used cars seemingly not an issue.

Rather than just keeping faded till receipts keep a file of the car's general history (MoTs, "road tax") as well as receipts and print outs for parts and materials (but not trivia like every light bulb) and keep it in a folder with individual leaves/envelopes in reverse chronological order with a summary of the main points at the front showing what was done at what time and mileage,  plus the latest MoT, "road tax", V5C.  Most potentials buyers are well impressed with this.  Plus it means you can quickly reference relevant information a potential buyer might ask or when search for relevant history yourself..

I'm a mechanic by trade so I can stamp my own book and I keep the parts invoices with the registration on as proof.
I agree with roottoot, I'd rather see invoices with the parts information than a service stamp, you can buy dealership stamps online for £20 and falsify a full dealer history.

The only time I'm bothered about main dealer stamps or records is when the car is within warranty. I'd rather buy a used car from an enthusiast whom had serviced it himself & kept records. 

I'll be servicing my recently purchased Octavia yearly, even though it's on the extended service intervals. I see no harm to 5k oil change intervals if that's what an owner decides to do. 

I've also bought many used cars in the past with a fdsh (none manufacturer specific) & they've never had the pollen or air filters changed, after I'd checked them myself afterwards. 

Now I've bought a Skoda I hope I don't have to visit a main dealer for a very long time😂
