You might want to do a little research on the additive Zinc. There are a number of reports of flat cams in older engines and more due to the EPA forcing the removal of the very effective anti wear agent “Zinc”. Some of the currently blended oils have zero Zinc. You can argue the point, but when you buy a $58,000 pickup truck with a diesel in it, you want it to live as long as possible. IF you don’t have a Cat, and it’s legal to run this additive, you might give more thought to which oil you use in your truck, and what you might add to it. There have been tests that have demonstrated Zinc does wonders to extend engine life, and one example is reduced wear in pistons, ring lands, and more. Engine manufacturers may be willing to say things are just peachy without these popular anti wear agents, but they care most about meeting warranty and getting along with the EPA I would think. I think what we need do is watch what the fleets of over the road trucks do… I doubt they’ll want to live with any less service out of an engine, I hope we hear from informed people as to what might work to assure the same or greater engine protection.
If you have older collectables or stationary engines, you might put this topic higher up on your “things to research list”. We should expect increased wear when we use lube oils without Zinc in engines with flat tappets. This could have a very significant impact on engine life and the real cost per KWH when you’re off grid and
forced to roll your generator on days the sun doesn’t shine, do what you can to protect your engine, and read about the anti-corrosion protection these agents offer as well. Well insulated Generator Sheds where temperatures are more constant, and temperatures change more slowly can help control condensation. This is a first step in controlling corrosion.
Here’s a few links, there’s lots of them. The PTFE crowd will claim their stuff is as good as Zinc.. but when the inventor and manufacturer of PTFE says it doesn’t offer benefits as an engine oil additive, why would you believe??
Yes… your right… I was happy to get the news about Keith.. 🙂
All the best,
