And there's a couple of different types of benzene as well I think. The list goes on and on and all the details. . .it may not be for everyone but I gotta say with a grin it did stop the ticking valve in my Jeep. The engine I have in it is a 4 cylinder and it's known to have carbon issues. Chrysler posted a Tech Service Bulletin back in 2004 to use a different spark plug to help prevent the problem. Carbon buildup seemed to be occurring with people who made short trips on cold days and didn't give the engine enough time to properly warm up. . .hence carbon problems. So after I started using the Marvel Mystery Oil in the oil and gas the problem permanently went away in about a week. When I did the first oil change after that it looked like black paint. . .tons of dissolved crap in it. That was when I had around 30,000 miles on it. Subsequent oil changes were never as dark. . .just what one would expect. . .plain old dirty oil. Now I've got close to 100,000 miles on it and it runs great. The front fenders are rusting but other than that I can't complain.
On another note. . .I've been using Castrol for years in my machines. . .just Castrol. I used to use what they called 20w50 Castrol Motorcycle Oil (non-synthetic) in my KLR, but now use the 10w40 conventional (non-synthetic) in both my KLR and Suzuki GSF 1200S. I generally change the oil twice a year and the filters once a year. I found the 20w50 was a bit too much for the KLR and I just started buying 10w40 by the case and used it for both bikes with good results.
I was thinking about sticking with a Castrol product for the Honda PCX when I got it and was going to bring up the subject at the time but from what you are telling me the "Edge" product is the way to go eh?. . .what do you use in yours. . .the 5w30 or 10w30? And would you say it was good from the git go once the factory supplied oil was changed out? Once I start with an oil I stay with it as to avoid non-compatibility problems with other brands/formulas. I planned on using synthetic in the PCX but have heard pros and cons about break in issues.
I don't do much driving these days, so I pay someone to service my Jeep once/year because I CBF'd doing it myself now I'm getting older.
I don't know what they put it, and I don't really care. It just potters along and doesn't do anything crazy. I'm looking to sell it, and be done.
As for what I put in the VZ-R and the PCX. Well, I've only done 1500km on the PCX, so it's only had a single top-up with Repco brand 10W30 semi-synthetic I think?
I wasn't fussy about it as it's just for top-ups until I put the BBK in. After which I will be using 5W30 mineral oil for 1000kms, and then switch to 5W30 fully synthetic.
The VZ-R just gets whatever 0W40 or 5W40 fully synthetic that's priced well on the day. It's only done 40,000km in the last 7 and a bit years, and it's not driven hard.
Back when I was a ratbag doing naughty things and tuning my Mazdas, I would only use Castrol Edge with oil and filter change every 5000km with upper engine inspection.
I use to drive the Mazdas pretty hard and get the headers glowing red hot, even cracking one set of stainless headers from going past the purple heat range into destruction.
So, the more I demand from my vehicle, the more fussy I am. In the case of the Jeep, it has an easy life. The PCX will be fussed over, with the VZ-R somewhere in between.
But you can only get Castrol Edge in 5L quantities here, so it's not easy to use with the PCX. And I haven't seen cases or carbon fouling in the upper engine of the PCX anyway.
I typically buy Motul or Penrite these days since they're cheaper, and just do Subaru Upper Engine Clean routine with injector cleaner in the tank occasionally on the VZ-R.
