The 15W40 (delo gold ultra) during the rinse....back to Caltex (Chevron) C3 5W30 afterwards...not sure how that correlates to running "two grades heavier than specified by the OEM", when it's one grade lower than the cold weather spec in my manual... but haven't seen any change in mileages on either the 30s, or the 40s.
Helix 15W40 with super cleaning agents came on sale for $14/5L, which is what I was running here, (bought 3 of them) at approximately 1,000km OCI (same filter) to see if I can move some varnish...not looking promising.
That's what's in there at the moment, and what I saw the 125C...only identified Friday...will run at least another week testing normal driving/with revs.
Rather than using the 10W30 in the stash (it'll keep), I bought

In the interests of science, I shook the bottle and a number of others in the shop, as some here recommend, but results are inconclusive at best.
