Gents,

I am sure that has been discussed many times but I am very confused since I discussed that with Triumph rep. He told since they have limited time, they check the oil level with the engine being warm. Put about 5 liters and run it for 5 minutes, stop it for 5 minutes and check. This is what I saw:

The Triumph User Manual says:
1. NEVER check the level when the engine is WARM
2. Ensure the engine is COLD
3. On side stand, start the engine for 60 to 90 seconds then stop it for 3 minutes and check the oil level

This is what I did the next morning, engine cold, in my garage, and got this:

If I check again with engine being hot, after a ride, and let it rest for 5 minutes, I got the first reading.

Whom to trust??? Triumph procedure, or Triumph Tech???

I own a 2.3L Gen 1 Rocket. Both Gen bikes use dry sump oil systems. Most of the oil is in a tank outside of the engine. The oil will leak down some into the engine over time. The Gen 1 2.3L bikes was always measured after running a cold engine for 60 to 90 seconds. then wait 3 mins. So that part is right. These bikes oil check is done with the bike in the upright position.

Now the Gen 2 2.5L bikes do it a little differently. And it was a big surprise to many of us as the new way just does not seam to be right. But it is as far as I know. Run the cold engine for the 60 to 90 seconds, wait the 3 mins, then check the dip stick with the bike on the sidestand. I know that seams to be a little nuts.
 
Understood, but that means that Triumph's tech are always doing it wrong since they have to work on warm engine since customers is waiting to get his bike back in less then 2 hours? That will be scary because looking at mine in the morning, I am below the min. If they are right, by adding oil I will overfill, if not, they are taking the risk of killing engines by running them low on oil... would be nice to have Triumph clear input on that!
