Engine oil Kendall or OEM FORD

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.

I bought a new air filter for carb. I reinstalled the front engine pan. I did an oil change. VW specialist recommended I go to Kendall 20w50 to fix the oil light at idle.

I use full synthetic kendall and it runs beautifully.

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)

I red-line 1st and 2nd gear when merging onto highways from the on-ramp. But then cruise at 100 kmph on the right lane. Gotta have fun when you can! Ensure that **oil** temps are good, not just the coolant.

Kendall GT1 10W30 - Volvo filter 1275810

Done every 5k miles by my local Volvo specialist because that's their default and I like it to be checked out frequently. It's the oil they use. 179k miles

I switched to Kendall GT-1 20w-50 high performance and I highly suggest it. You can get 12 quarts shipped to your door from Amazon at a good price.

Ran Kendall 15x40 for a number of years, ran Shell T4 till it got oddly hard to find, currently running Delo 15w40

I have a 98 TDI with 269k and I had an 06 TDI with 131k. I have dumped the unfiltered engine oil after each change into the tanks of both cars since I've had them (Beetle, 98, got at 230,880 miles). They burn fine.
