Question for youse' guys..
I put a 15 oz. bottle of VSOT into my 1.6 with 4 quarts of M-1 0-40. I need the 0W in the cold, it quiets the startup. This is with a PureOne 14459 teeny filter. Immediately after the addition of the VSOT, I started getting that cold-start tap. The oil is thicker on the end of the dipstick, especially when cold, but I do notice that the oil clings to the cam lobes, looking through the oil-filler when the engine is idling.
A BITOG member sold me a half dozen 24458 Puro Premium Plus filters (these are oversize 14459). I removed the little PureOne filter, installed one of the 24458 oversize, put back one quart of oil (Ok, ok, standard dino Exxon SuperFlow 5W-30), and lo and behold, no more cold-start tap.
Question is, was the little PureOne responsible for the tap after the addition of the VSOT? Or did the larger filter help matters? Or is it simply the fact that I've reduced the ratio of VSOT-to-oil allowing a better cold-start flow?
I have to admit, though, seat of the pants observation, the engine runs much more smoothly now, and I could swear the throttle response has improved greatly. Once this thing comes off the cold fast-idle, I can barely hear it turning over at idle anymore. Amazing. I wonder if a UOA would shed light on my instincts regarding the improvements.
