Wow! Ignorance abounds..frequent drain intervals are a necessity no matter what kind of oil you use. 3 thousand miles of oil contamination is still reason to change the oil no matter what kind you use. You talk about heat? How hot do you think your turbos can get? Regular oil wile coke up much faster than synthetic oil. And if you still have the auto stop start,you increase your start ups by a huge margin, and start up is the place where most wear occurs. Synthetic oil flows more freely during cold starts.plus the better additive packages and detergents. There is no comparison synthetic is vastly superior in every way.I suggest you find better sources for your oil information.you have been mislead.
The 3k mike oil change interval for the most part went out the window many years ago.
So We’ll have to agree to disagree.
Yes turbos get hot and start stop is a terrible idea anyway you look at it but under normal driving conditions these two things nor is anything else breaking down a synthetic blend at 5k miles.
It is just not and I have done plenty of oil analysis over the years that show my oil has not degraded in a fashion to be an issue. Nor have I had an engine oil related issue.
Ford recommends 12 month or whenever the computer tells you to swap your oil using a synthetic blend on these motors. If synthetic was needed Ford would require it. I change at 5k and I have yet to be below 40% on this rigs oil life meter. I have not done an analysis on this truck yet but I am due for an oil change here in about 500 miles an I’ll post the results.
Yes, synthetic is better in certain applications but only when you surpass the capabilities of a synthetic blend is it worth the extra money. And I have found zero indication that regular daily driving does that.
You mention fleet and performance absolutely a great place for synthetic.
Just like the intel i7 processor blows an AMD A8 out of the water in processing power but the added cost only comes at a certain threshold.
The i7 I have in my dedicated security camera system is needed to keep up with multiple continuously recording high definition cameras.
I’d be doing nothing but wasting money even though technically speaking it is a better processor in every way by having it in my office computer that does nothing but internet browsing and word processing.
