Changed the oil early in Dec. 2018 with Castrol Edge 0W-40 and drove 10,000 miles in 9 months. My driving consists of an ordinary mix of short-tripping (between home and gym), commuting (14 miles each way) and highway driving (3 day-long trips). VW recommends a 10K OCI with a VW502 spec oil. I wondered how suitable this interval was for my situation and sent a sample to Blackstone Lab. The results are unremarkable and show that the 10K mile OCI was reasonable - at least for my driving style.

A few observations:
1. The 1.8L engine holds 6.7 quarts of oil, so there is plenty of additive reserve and capacity to hold contaminants in suspension over the full interval. This probably explains why adequate TBN (3.3) remained at the end, and the insoluble contamination was modest (0.8%). However, if my engine held only 4 quarts, I’m not so sure the results would be as good.

2. The viscosity at 100C declined to 10.7 cSt, which is in the middle of the SAE 30 range (9.3-12.5). Per the Castrol spec the viscosity of new Edge 0W-40 oil is 13.2 cSt. Clearly this version of Edge is not as robust to viscosity breakdown as Edge 5W-30, which Castrol claims is “3x stronger than the leading full synthetic against viscosity breakdown”. Nevertheless, SAE 30 is certainly acceptable, and xW-30 oils are marketed which meet the VW502 spec. So, for my ordinary driving the partial loss viscosity is not too concerning.

3. I don’t have a sense for the significance of the iron level at 27 ppm. As the lab commented, iron increases as the drain interval is extended. Is there another oil out there that produces a lower iron level for the same OCI?

I agree. You'll find most 0w40's are going to drop into the 30cSt range, especially if there is any fuel dilution. Generally speaking (and I think this oil is no exception), a larger spread has more VII's therefore the percentage viscosity loss will be higher due to more VIIs. The results would likely be the same with M1/Pennzoil 0w40 as well. The oil did have life left in it and there was no sign of any oxidation. I think the wear metals are good.

0W-40s are ( usually ) just barely 40 grades, i.e on the very thin end of 40, and usually drop down to a thick 30 even without any fuel dilution happening.

I'd give Mobil 1 ESP 0W40 a try, if you're so inclined. Two runs would be best doing a UOA on the second run to be certain all of the Castrol is out and the results are more accurate.

It looks like the oil did it's job. We have a 2014 Jetta 1.8 TSI and run Castrol 0w40 for 5,000 mile intervals. We both live less than a mile from work and use the car for running errands, so it sees a lot of short tripping.

I would strongly recommend a 5000 miles interval if you plan on having the vehicle for more than 150,000 miles.

There was a time when most motor oils could easily handle 10,000 mile OCIs on modern engines. .In fact, I wrote a lot of articles about this just a few years ago.

https://www.yahoo.com/news/bp/the-g...-oil-change-works-for-you-134321080.html

A lot of today's engines, especially those that have direct injection or turbo chargers matched to a high compression engine, are incredibly hard on the oil. There are also engine designs that have timing chains which have lubricating issues if an oil is consistently left over a very long period of time.

If you are a highway runner who doesn't rev your vehicle that much, you may be perfectly fine. But even then, if you want to keep this vehicle beyond the 200k mark I would simply invest in a 5,000 mile OCI. If you have a filter designed for longer intervals you could possibly change that every other time you change the oil. But if it were me and I was eliminating another car expenditure until EVs become a viable alternative, I would look at making it a 5,000 mile OCI all the way around.

All the best!

Steve

This topic should bring out the "you better change it more frequently than the owner's manual says to do it or you will be very sorry as your engine will not last long" crowd.

10K mile oil changes with that oil looks good
Spend your time and money on something else besides changing the oil

unless using a real group IV +or V synthetic 5000 or 6 mo is a good interval for your driving habits. fake synthetics as most are with wider spreads REQUIRE more viscosity improvers that break down + todays DI engines are hard on oil. unless you trade often 5000 - 6 month oil changes are cheap insurance. in your area a 10-30 synthetic in summer + 5-30 synthetic in winters may do better. 200 thou on my traded 2001 jetta 1.8 T with about 275 TQ + HP using 10-30 real synthetic redline year around in Pa 10 thou intervals, but only port injected! a good thing in my book until VW brings both to USA as in Europe!

So here we have a very good UOA on the manufacturer recommended interval and immediately three or four people recommending changing the oil twice as often confused

The 1.8L engine holds 6.7 quarts of oil


I think you mean 5.7. I hope so at least. It's 5.7 quarts or 5.5 Liters (I like 5.5 liters because it's easier to measure if you buy oil in liters).

Good results though. I'm nearing 10000 miles on my OCI with Valvoline MST 5w40. No issues with burning oil or anything.

Its gotta be 5.7 as the sump for the 2.0 L EA888 is 6.0 quarts.

Shocker. 10K OCI shown to be just fine by UOA.
