Engine oil RAVENOL or OEM FORD

My Ford Freestyle with a 3.0L takes 6 quarts, while my Pontiac Grand Prix with a supercharged 3.8L takes 4.3 quarts. Go figure. I was shocked when I saw how much oil the Ford takes.

my 2011 ford fusion oil cap has 5w-20 but when i put that oil, engine noise become loud. Only 10w-30 noise is lower and engine smooth.

Even Ravenol, which is pretty expensive since it is made in Germany from Group V base stock. Great stuff.

I used to have castrol but since i chiptuned my octavia i switched to ravenol and the oil temps went down a good bit and it doesnt use any oil but that could also be because the old oil was 0w20 and the new one is 5w40

Last month I replaced the valve stem seals and it helped massively with the smoke. It doesn't really smoke much anymore, there's definitely still small puffs when taking off quickly, but nothing that I can see in the mirror.

I go with 10w40 Ravenol TSi

I use Ravenol which is 100% PAO base stock.

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)

The oil i have run: VW brand, Castrol and Ravenol all 0w-20 that meets 508/509. Basically on cooler outside temperatures the oil does run slightly higher than on hotter days.
