Thanks for the quick replies, I appreciate the input. Dad has been running the Amosoil Signature Series for about 100k miles now. He hasn't ever used any cleaners or anything like that in the oil, but he does put Lucas in the gas tank every now and then. As far as use goes; he hauls the...

This vehicle is a 2002 Chevy Silverado, 4.8L V8 This is the first oil analysis done on this truck. This is my Dad's truck he was running a K&N air filter that he changed to a regular filter after receiving the report. The comments section of the report mentions possible break in period of new...

Originally Posted By: danthaman1980 In the OP's instance, the TBN sure is low for such a short run, ESPECIALLY since he added a quart of make-up oil and ESPECIALLY since, if his 5.3 is anything like mine, the sump is 6 quarts to start with.... that means the TBN depleted to 1.3 on 7 quarts of...

This is the first UOA for my new-to-me truck. 2007 Chevy Silverado with a 5.3L V8. The truck is burning oil, probably because of Active Fuel Management, that's what I've read anyway. I switched to Penzoil High Mileage in 5w30. No real reason other than to try something different. Blackstone...

Well, I decided to go with Maxlife synthetic blend and a M1 extended performance filter. I will check the oil every week when I put gas in the truck and I will send a sample in for analysis before adding oil or changing, which ever comes first. Thanks for all the suggestions. I'm learning a...

2007 Chevy Silverado Bought the truck used this was my first oil change, I have know idea what was in it. In: Valvoline Maxlife synthetic blend, M1 extended performance oil filter.

I just read the UOA article that explains the "stuff" found in an analysis and what they likely mean. I found the explanation of %Fuel interesting. The author attributed idling has a potential culprit for increased raw fuel. I have been idling my engine until the water temp gauge starts to...

Thanks for all the replies so far. A bit more information... The truck is rated to tow 7500 lbs. It has a Gross Combined Weight Rating of over 13,000 lbs. I plan on sticking with 5W30 per the owners manual (unless there is good reason to deviate, lets face it, I'm not worried about a warranty...

Before I found this site and started reading about oil I purchased M1 EP with a M1 filter for extra capacity. I'm starting to think this may have been overkill. I am considering bringing it back at this point and going with one of the above recommendations, haven't decided just yet. Thanks for...
