recommend and why would you recommend it.
i don,t use it. if your engine smokes or anything like that then i would say put some additive in it, but if your engine is running good, keep it out. after all, most oil has additives in it.
There was an article on Consumer Reports a few years ago that examined whether the additives did any good. They found that they didn't have an effect at all. In fact, oil manufactures said they spend millions of dollars formulating their additive packages, and dumping in other chemicals defeats the purpose. The article also found that there was no actual benefit to using synthetic oil over conventional oil. There is nothing you can dump into your engine that will fix something that is broken. I once read an article that recommended using high detergent diesel oil in engines that were showing signs of sludge build-up, but that was the only scientific sounding advice I have ever heard when it comes to deviating from changing your oil at the factory intervals with an appropriate grade of SAE oil. The only scientific proof that additives help comes from the additive manufacture, and the same goes for synthetic oil. That only goes for crank-case oil in automotive engines though. Motorcycles, gear boxes and transmissions can be a different story entirely.
unless your car smokes no reasion to use oil additive.i do throw in can of injector cleaner every fall.
