I have read about the VCM Muzzler, how long have you had it...any problems? I'm gonna go w/ 5k and try a 5W30 syn. I was actually thinking about a HM oil...??? [/quot
I bought our Odyssey used in Dec 15 with 61k. I had my Honda mechanic check it out prior to purchase, and we felt it had suffered no ill effects of the VCM. I installed the Muzzler the day after I brought the van home (engine must be stone cold). We've put 5500 miles on the van since then, and the van runs great, just like our previous 2004 non-VCM Odyssey. Gas mileage is better than our 2004.
Go over to Odyclub.com. There are a ton of posts on the Muzzler, plus some interesting info on how it was designed and why it will not harm your engine in any way. No one has reported any problems, and some have put 40k + on their Muzzled vans. Owners of 2016 vans are getting the Muzzler. It is a 5 minute install, sold by Odyclub member Verbatim up in Canada. Looks OEM. Besides saving your engine, the active Motor mounts($$$) will hopefully last longer. It also works on Honda Pilots.
I would not have bought this van if I hadn't known about the Muzzler. Who wants a possible ring eating, oil burning nightmare!
