Hey guys,
I've lurked here many years, but I never posted a UOA. At around 98,500 I had to replace the intake manifold gasket on my 2003 4.3 Silverado.
I am the original owner of the truck and just about all of the oil I have ever used was Mobil 1. I change when the oil life monitor light appears. I do NOT use this truck on a daily basis. However I do tow 1500# occasionally and do use it on our vacations.
This was my first time using Mobil Super Synthetic. I used Mobil Super Synthetic because I got it cheaper than Mobil 1.
At the time I did this UOA I replaced Mobil SS with Maxlife 10w30 SN. I am using Maxlife because I have a very minor oil leak from the oil pan.
In the past I used AC Delco filters. I stopped using AC Delcos because the PF 52's I use (oversize) are ecores. So I use the classic Purolator filter, not ecore, oversized.
Should I: switch back to Mobil 1 OR a different oil, keep using AC Delco filters?
Guidance, suggestions, recommendations are really appreciated.
Thank you for taking the time to read my post.
