Oil change with synthetic

Newer computers don't base oil change intervals off of mileage

My trucks F150 2012 oil sensor will automatically adjust to synthetic based on the oil properties. I don't know what parameter it is looking at but the life is a lot longer when I use synthetic. In other words, a newer vehicle may not have to adjust anything and should be able to comprehend both

I always put synthetic, but then realized we always listen to the computer for oil change intervals. If they base that off standard oil, is it worth paying the extra for synthetic if I still change it every time the computer tells me to?

If you use a premium synthetic it won't degrade as quickly and will extend the change intervals. But you still need to check the dipstick to assure your engine doesn't consume oil past the minimum fill level.

I would also advise you use Seafoam on the upper intake manifold a few days before changing your oil. This will clear oil deposits from the upper end of your motor and allow them to settle in the oil pan. Then when you drain it out, it'll take some of the carbon buildup with it.

I use Amsoil 5W-30 and an Amsoil filter. It's rated for 15k miles but I change when my computer tells me, which is typically around 8-10k miles. I drive a 2010 Yukon Denali so your wife's vehicle should have the same oil life meter and computer as mine.

Here's an interesting comparison showing the versatility of synthetic oil:

Full synthetic costs the same as standard oil in the long run. If you have to change conventional oil every 3,000 miles, that's 3 oil changes at $30-$40 a pop vs. 1 oil change at $100.

I've been using synthetic since it came out. I go 5K then change filter and top off level. Then 5K more before complete change. Works great for me.
