What oil is everyone using

[Walfers62]

Thats it and best to stick to it whilst under warranty. Another good one from their range is HPR5 5w40

Sorry, 5w40. Just getting used to the new content system with captions, descriptions and comments. I'll get there

Hmm, so 5w40 is better than 5w30?

I don't understand why they would be using Dexos2 since it's designed specifically for diesel engines and Dexos1 is the oil for petrol engines. Refer below:

I may have got the numbers wrong when I typed it in, as my Captiva was diesel and there was Dexos2 oil put in - just checked my invoice. Sorry mate

5w30 is dexos certified...hpr is not
Is your car under warranty ?

I run this device which changes lubrication duty, cooling and its flow characteristics, engine builder specified 5w40 to suit hydraulic stuff (VVT, AFM) and e85.
View media item 116I consider the two weights are very much the same in practicality, there is a slight but noticeable difference with 5w40 being quieter when oil is close to 100°.

Still under warranty, will most likely tune it anyway

Stick with gf5 5w30

I changed the oil in the Redline the other day at 3500km and was black as. I forgot to check to see if there were any metal filings in the oil. I usually change the oil at 7500km as the 15k is way too long between changes.

Castrol Edge will have a Dexos approved oil soon. When I rang their technical phone number, the bloke was happy to have a chat but definitely towed the company line and said they can't recommend using any of their products until their new Dexos oil.
We also chatted and laughed about how much bloody money GM was making getting certification from all the oil companies. It must be very costly having to have products certified to API and/or ACEA and/or ILSAC and now all the manufacturers own certifications.

I've gone with the Edge 5w30 ACEA A3/B4 as that european standard is more leaning towards motor protection than fuel economy and emission system longevity, than ILSAC or Dexos tend to be.

I only swapped out the Mobil 1 0w40 for the 5w30 to see if it was causing this ticking noise I get when warm. It wasn't the cause, and I'm pretty sure it relates to the factory tune as it only ticks when its filled with 98. No idea why its doing it (any idea @monstar ?)

Why the non genuine filter? The genuine filters are cheap as chips.

I was thinking about it but decided to use a different brand so I know if the dealer workshop changes the oil filter for its scheduled services.

Just put a date on it with a marker when you out it in
