Consensus is Valvoline 20w-50 is good oil to run. You're the only one to suggest otherwise,
yet offer no proof why.

Right. Synth allows that leakage by removing old deposits. Does synth eventually build up
deposits of its own to replace the dino deposits it removed? Or does the car continue to
consume synth forever after at the immediate post-changeoverrate?

That's how you learned to read?? No wonder you're having such trouble. Sadly it
seems to have impacted your writing skills as well. My condolences.

Anyway, the question I'd really like an answer to is this: In cases where changing over to
synth on high mileage motors leads to oil consumption once the synth is installed, does that
consumption eventually dissipate to pre-changeover levels - e.g. does synth, after removing
the old deposits, build up its own deposits (varnish, if you will) to 'fill in the gaps'?
Anyone know the answer to this?
