My commute ends with a fair amount of city driving before I get home so while I operated the engine for more than 20 minutes, the majority of the final miles are stop and go city driving. It's my assumption that this is cause of the trace fuel. As far as I'm concerned, as long as it remains a trace amount I'm not too concerned.biodieselrabbit wrote:Thanks for posting your analyses blindman10. Did you run the engine at highway speeds for longer than 20 minutes before sampling? Is that the reason for the trace fuel showing up?

My Mom's Vibe:
Based on their suggestion, I will be moving from a 2500 mile oil change interval to a 5000 mile oil change interval.
I know! I started laughing when I read that! What a small world !Rayven01 wrote:Awesome that your report writer was a fellow vibe owner!
No they didn't. We have been using Penzoil for as long as I can remember in all of our vehicles and have never had issues with it so I don't see any reason for switching. Penzoil has always served our vehicles well; my dad's 2001 s10 has ~280,000 miles on it and is still running great. Our 1994 Pontiac Sunbird LE Sedan that we junked back in January (due to rust) had 268,010 miles on it and still ran great.chiadog wrote:Hey Vibenvy,
Did Blackstone recommend an oil BRAND that has a better TBN than the pennzoil 5-20 that was tested?
What they said specifically was:Chiadog wrote:Hey Vibenvy,
It appears to me that the oil test folks are saying you are using an inferior oil. From what I understand, "You might want to choose an oil with a higher TBN" means your Pennzoil came from the factory with insufficient additives to last the long haul. Am i missing something?

I should send some from my 03 GT with 280k on it for fun.
I used them a couple years ago but for my 1992 F-150. Mainly because I went over SEVEN years between oil changes and was curious as to what damage I did to the engine, if any! Turned out it wasn't that bad considering it was just under 10000 miles since the last oil change. Truck is sitting at 60k original miles. I bought it new 28 years ago
I need to see said truck... All I ever see are the Pontiacs in the driveway!tpollauf wrote: ↑Mon Aug 19, 2019 8:30 amI used them a couple years ago but for my 1992 F-150.

Sounds like you might have been just as well off renting a truck when you needed it, and have the extra driveway space!tpollauf wrote: ↑Mon Aug 19, 2019 8:30 amI used them a couple years ago but for my 1992 F-150.
