Decided to try out a newer and lower priced product from Amsoil. SynBlend in 5w30:
https://www.amsoil.com/p/amsoil-5w30-synthetic-blend-motor-oil-sb530/?zo=515729
Understand, I am not an oil expert like some on here, but I do know that Amsoil makes good stuff, and they dont hold much back when it comes to spec bulletins. It meets API, and Dexos1 Gen3, so I know it is good for my daughters 04 Tahoe. It was up for a change after nearly 5k, nearly 6 months.
I plan to do two changes, probably at 3k-5k and do two oil analyses. To hopefully show a small trend, and show the performance of the oil.
The engine runs like a sewing machine, with no noise, good power, and get about 17mpg highway.
This engine, 5.3LS, has been changed regularly, for the last 4 years, and although it has typical leaks for a vehicle of its age, it uses no oil to speak of.
This first change will be run through a Champ XL synthetic media filter, and the next run through a ACD UPF46R, as those are what I have in stock.
The usage of this vehicle is typical, a daily driver. It gets started in the morning, with a short warm up, maybe 5 mins, then driven to work, which is 10 miles away, mostly at 55mph or so. Once a month. it is driven about 7 hours round trip to Wilmington, NC.
The oil that came out was Napa 5w30 Synthetic, with a Napa Gold filter. (Likely the last Gold I ever buy).
