Not to be an ass, but why? If you're not using any oil but that specified by Ford engineers to avoid voiding the engine warranty, then why would you use an add-on component to the oiling system that wasn't specd by Ford engineers that could just as easily (and likely) void the warranty?
Using a accumulator is not a bad idea. That's why I mention it. Nothing wrong with using a accumulator to pre lube your engine, it may also save it in the case of oil starvation or if it loses oil psi do to air intake during hard cornering. It's cheap insurance. Once it's installed you really don't have to do anything to it. Especially if you get the electric solenoid valve. No car manufacturer is going to put everything on a car to inhance its performance or longevity.
And so is using a lower viscosity oil in cold weather. The point is that it seems strange to defend the expertise of Ford engineers against a suggestion of others to use a different oil, while at the same time defending the personal choice to ignore their expertise and add an accumulator.
Oh you mean how the exact same engine in the coyote people were told need 5w20 but the pp called for 5w50? A car advertised for track, ford isnt going to tell those owners 5w20 is okay and let them go to the track and risk failure. 5w50 is too much pressure for a daily street driven car that runs errands or toots around town. They never gave those coyote pp 5w50 users an alternate weight and people have switched and the car is better off. Same for the 302 boss. This will be no different. Most people buy a track model car and never use it for its intended purpose. A weight suited for that purpose is better for the engine typically. Do you think most older M series owners needed 10w60? Absolutely not. 10w30 was fine. Its that whole intended purpose thing again. An i currently am a master tech at bmw. Current weight now is 5w30 even for M cars. It helps with fuel economy and they know so many people arent tracking their M cars. If a bmw needs thicker or thinner weight etc as long as it meets the current standard we wouldn't not warranty it.
I worked at ford during the time of the most recent 302 boss. I know what they will cover and wont. Here is a post of mine from another thread.
That's because the R-C has a dry-sump ;) -I agree that the accusump for oil starvation or pre-oiling is not necessary.
You know that 5w50 mc is some of the worst oil on the market in that weight right? If you like running an oil that sheers down to 5w40 in 1000 miles or less. You run that garbage.:lol:
The engine was designed to use it and it's raced successfully with it, so... :shrug:
The engine was designed for race tracks. 95% of them will not be used as intended so to use an oil that was intended for racing, on the street that giving you very high oil pressure is stupid. The only time motorcrafts oil is acceptable is in non performance vehicle's. Bmw german castrol wasnt that great either. People should either use pennzoil ultra if they cant afford amsoil, if they can use it. If someone has a need for an 5w50 the last thing you want it to do is sheer down to a 40. You want it to do its job and give you that protection. Motorcraft is garbage. This is the blood of your car, not something you trust to a synthetic blend or improper weights for the intended usage. /thread
