Gen 1 coyote Tick/knock

[S197sito]

I have a mustang 2012 Gt gen 1 coyote I recently just bought service has been done on it throughout the years but recently I started to notice that after driving for a while the engine starts to knock especially at low rpm’s does not do it at idle sometimes it will I’m not sure if this is normal or not I haven’t noticed any engine power reduced and another thing is that my manual trans starts winning after driving for a while most noticeable in 1-4 5-6 is quiet I’m new to the coyote platform so if somebody can help out that would be great car also has 116k miles on it

When was the last time oil was changed?

I’m honestly not sure but I’ve had a feeling I should do it the car is my daily so I’ve already put about 1200 miles on it what brand of oil do you recommend

Look at your vehicle manual. It will tell you all the service requirements needed.
