I use Castrol Edge 5W-40; works just fine
Glad to be of help helmyv5. In one message, I mentioned I'd try a more expensive oil next time. I've now been running Castrol EDGE FST-Ti for the last two oil change intervals. Normally, oils are very hard to tell apart from one another (Like how the engine sounds, gas mileage, other \"seat of the pants\" stuff) But, this time I can definitely spot one difference, which is noticeably less sludge in the PCV system than with the Helix Ultra.
Remember that the rotary engine burns oil by design and does not particularly like eating synthetics. Expect to use old fashioned dino juice and change your oil every 3000 miles.
Castrol Edge Professional 0W-20 seems to be the VAG recommended oil for their 508.00 requirements. Everything I’ve read about the 0w oil has been positive as it holds up extremely well in cold weather and severe heat.
I buy the Castrol Edge OE 5w30 that DAP sells and change the oil preemptively, always with VW brand filters. Has all the VW certs necessary, is what VW uses, and doesn't break the bank.
at 30K and third oil change @ 10K, my oil analysis went to the waste oil furnace, it said the oil was perfect. First change @10K was Castrol 0W40, last two were Mobil 1 0W40.
Either Mobil 1 or Castrol GTX - never had oil issues with either one.
Running the OE Castrol 0w-20, pushing the car very hard up a twisty road in NC/SC, I saw a maximum of 235F with an ambient temp of 75F. My averages with normal driving are close to yours. These temps are well within the oil's capability.
i been using it religiously for now 85k miles, i have tried Quartz Ineo 5W30 502 Spec oils made my engine produce more heat and valvetrain noises. The Castrol Edge 0W40 I use now tops out at 212, normally sitting between 205 and 210. With the 5W30 Quartz it was constantly sitting at 227-237 which is pretty significant.
I put mine in around 20k. The first change I did - it had 2 small metal shavings. I got very nervous. Ever since then there has been the powder you have in the pic above. Sometimes more sometimes less. The 2 times I have used Castrol I found more than other times (This could mean it protects less or that it carries the particles better than other oils). I will only become worried when I start seeing shavings. To me it's only an additional monitoring system. Like in a tranny - powder is ok, but shavings mean save up some cash. oh and my car is now at 125k.
