Oil: synthetic vs blend vs regular 2010 F150
I'm just wondering what's more beneficial for my
motor, full synthetic, blend or regular oil and also if
there's any benefit to using high mileage oil since
my truck has 84,500 miles on it?
Frequent changes are the key to engine longevity, not the type. Keep using what you have been. High mileage Motor oil has additives to swell gaskets to slow down leaks.
At 85k you should not need High mileage oil? Like said frequent changes is key. Full synthetic is best. Blend is higher grade regular and is not actual a blend of regular & synthetic and it will last longer than regular oil. Regular is fine just change it before it starts to darken up even if its before the owners manual says too. Learn to change your own oil if possible. Synthetic will last much longer, 10,000 miles or more. I like to keep mine from getting dark and change it well before it does turn black because black oil is burned oil. If I buy a auto with darker oil than I like I will use some cheaper oil and change it out with a new filter and put a few hundred miles on it and change it again with premium oil and filter and open up the oil filter to see if I can find any tiny bits of metal and see how fast the oil had turned back dark again to gage the internal wear and if I want keep it or buy if it it was done before purchasing or if its worth a rebuild in the future or estimate how far it will make it before it needs rebuilt.
Synthetic oil is good for high performance vehicles. Ford dealers use the recommended BLEND of synthetic and regular oils in their oil changes-or should. Synthetic oil is much thinner and will tend to leak through aging gaskets and seals. It also cost a lot more. I would suggest using the oil that your owners manual recommends. It was made to meet the specifications of your particular vehicle.
