My son just recently changed the oil and filter in my 07 F150 (4.2 V6, 132K Miles). I bought and used VML synthetic 10W30 and a FRAM ULTRA XG3600 oil filter. I received a coupon in the mail for $8 off of (2) 5 qt. containers,or, (10) qts. of any Valvoline oil. My son used the other OCI on my g/f's car.
This is the first time I have ever used 10W30 in this engine. And, it has never ran as quiet as it currently does. I did some research on the VML 10W30 oil and it stated the Noack % is 6.3. From what I have read here on the forum is that an motor oil with a low Noack % is a better oil. Is this true, and, is this why my engine is running the quietest it has EVER run since I have used the 10W30 oil in the engine?
BTW, it has yet to have ANY clatter or ticking upon startup.
