the car still has the power, i am able to overtake the highway merges on relatively cold engine (driving off parking lot, less than 5 minutes later, highway), idle is nice and smooth, no spikes from cold starts, no dips... the coil has resolved that issue, the MAF seems to be OK, as the engine stumbles when i disconnect it while idling...

The blue smoke... it has reduced its manifestation (can't be objective here, did not use any measuring tools), but before, I would be at my traffic light at my neighborhood, and cloud of smoke on take off (not real Formula 1 take off, just pulling from a stop light), now there is no plume of of smoke from the same light... but, there is still cloud in the rearview mirror, if i am idling too long on the highway (I-95 is a parking lot after the DC people finish their workday)...

I suspect that the "reduced" (real or perceived) smoking is due to a slightly heavier oil used, 5W40 instead of 5W30... from what i read, the racing cars use something like 10W60 or whatnot... I am not going to use that by any means, but oil grade might have something to do with reduced smoke...

Also, I have Auto-RX in the engine at this moment, do not know if the presence of that chemical alters the equation or not - could it smoke more or less because of the Auto-RX?

Next thing is, to see if using Liqui Moly full synthetic 5W40 oil is any better then using Castrol... price difference between the two $6 in favor of Castrol when Castrol is on sale, or $30 in favor of Moly when Castrol is at regular price - we are talking about 10 qts of Castrol vs 10L of Moly...
