Engine oil IDEMITSU or OEM Volkswagen

Im replacing mine soon...though since switching to 5-40 oil (as per recent VW specs) my oil consumption is far less than before.

Once the oil temp reads the temp number, you're all set to do what you please.

Subaru OEM oil is Idemitsu 0W-20. I currently use Idemitsu Zepro\* 0W-20, a high-moly formulation from the same manufacturer.

That's the wrong oil. You want the Idemitsu eco gold medalist advanced moly 0w-20, which is basically the same as Mazda oil(Idemitsu makes the mazda oil).

Idemitsu zepro eco medalist advanced moly 0w-20. Basically the same thing as Mazda's oil.

I've changed my TDI's oil every 10K miles since it was new. It currently has 330K miles on it and runs like a watch.

I've been using these docs for a while now, and am incredibly grateful for you sharing them. With that said, I just noticed something that's news to me. Both the \"Revised Oil Capacity Job Aid\" and the 2012 vs 2013 fluid capacity charts show a 1 qt decrease in engine oil capacity between 2012 and 2013 MY. I've always heard there were insignificant, minor changes between the model years. I've been putting 5ish into my 2012 and it's always been full according to the dipstick.

You don't need to add any more additives to modern day oils. You said you will be using Mazda 0W-20 oil? This is one of the best 0W-20 oils on the market. It is made by Idemitsu for Mazda. It has very high Viscosity Index of 221. Most 0W-20 oils are around 170. This means it is one of the lightest 0W-20 at start up. This is what you want in the winter.

I had the same problem with my 99.5 VR. I now use 5-50, problem solved.

We had 50700 VW spec oil in for 4,000 miles on the oil and 4,700 miles on the engine. The iron wear rate was about 15 ppm/1000 miles. The Longlife III oil did have impressive viscosity holding charictaristics. I did not care for the way the oil film of the 50700 wetted surfaces, it fisheyed on plastics.
