On a side note, if anyone really wants to see what their oil change interval should be, just get an actual oil sample analysis done. Per the lab reports, I can get 8k miles on quality synthetics and still have a good safe margin for oil life.
Ford is telling me to change oil at my Focus every year or every 15000km (9300 miles)
Thanks - I just ordered 2 5-qt jugs of the 5W40, less than $25 each and free shipping. We use this in my 2016 GSW and my wife's 2007 A4.
I throw valvoline 5w30 euro spec (vw 50700) cause it was cheap on Amazon.
as a small engine mechanic at my shop we use the Briggs and Stratton 5w 30 for everything because all we’re fixing is snowblowers but for my personal machines I either use valvoline or amsoil
Back when I dailly drove my 05 I went 10k fuel and oil. Donaldson filters and Valvoline premium blue oil
I run Valvoline VR-1 20w50 in my '74. It is straight Dino oil but it has a higher amount of zinc in it which solid lifter cars like ours love.
Valvoline max life kicks ass.
Valvoline max life kicks ass.
I'm using "Valvoline Modern Engine Oil" since they have patents and claim to have some chemistry there to keep the valve stems more carbon-free.
