Thanks for all the great information guys! I just bought a used 2013 VT (still under warranty!) and I love it! After searching here quickly I had some PUP 5W-30 put in it then went on to read about this whole -40 fiasco. I'm sure it will be fine for these winter months but I guess I should be looking to switch over to 5W-40 come spring. Anyone notice a difference with the -40 over the -30? I'm up in Southern Ontario, Canada so I'm equally concerned with cold starts. Should I just throw in some -40 for spring/summer and switch to -30 for the colder months or will I be good with -40 year round?

40 vs. 30 has nothing to do with startup viscosity; that number is the viscosity at operating temperature.

5W is the cold startup viscosity. You should use a 0W or if you don't want to risk voiding the warranty, use a 5W PAO oil that has a very low pour point value.

Right, thanks it's been a while since I've had a car nice enough to warrant remembering that! I was more curious how much the climate would affect the heat sheering of the oil down to a thinner viscosity as I think that was the reason for the TSB switch to 5w-40. I assume there's going to be some sheering even in a moderate/cool climate, so the interval of changes is in the end probably more important than 30 vs. 40 (I'm pretty sure I read that on this or some other thread about oil already, but it is common sense). Still I guess it would be better to err on the side of caution with the 40, not like it's really going to lubricate any/that much worse right? And yes any tips to avoid LSPI are always appreciated, I just joined the forums and in the last week have read many of your previous comments on this subject and a few others. Thanks again for the info and welcome back!

Right I've got to look into getting/making one, that would certainly add some piece of mind as well. Are there any designs that work better than others? I see people also put them in series, I'm assuming to add to effectiveness. I'm guessing that you could improve the effectiveness of a single unit to perform the same as having two conventional ones in series to save some space. Essentially you're allowing the gasses to cool and giving them something to form droplets/condense on. Anyone ever think of finding a way of cooling the air more so that condensation would happen easier? Air conditioned OCC? :crazy:

I'm putting a single can VT-specific kit together but can't provide specifics here. Do a search for #velosterturbo on Instagram and look for a recent pic of dirty valves.

I found it, eww . . . that is nasty.
