September 24, 2009I did my oil change a few days ago and found what I'm guessing to add up to would be about a 1/4 of a teaspoon full or less (probably less). My 07 NNBS with the 4.8 just hit 21k. I have no big mods, Just a GMPP air intake and exhaust. I use castrol syntec 5w-30 and wix oil filters. I know metal shavings aren't good but do i have a serious problem coming up or should i just monitor it in my future oil changes and not worry about it for now? I've always thought that castrol was good oil but could that be my problem? Possibly not getting enough protection? I dont beat the truck and i dont tow anything. Thanks for the help, Justin

September 24, 2009i dont think you should be seeing metal in the oil ever or theres a problem...i see it with the work trucks that have almost 300k on em but even my truck with 115 doesnt have any....how long do u go between changes? is the oil still full?
September 24, 2009I don't go any longer than 3k and It always stays full. I never have to add a drop in between oil changes. Plus i always let it warm up for a couple of minutes in the morning before i take off. I never just get in it and go.
September 25, 2009Castrol is good oil and I don't think that's the problem. Every time I changed oil in my 05 i had a grey metal sludge/shavings attached to the drain plug magnet, I think its normal .
September 25, 2009Your truck is too new for problems/irregularitys if you ask me... My 01 with 60K is running great and oil changes are always normal. You should still have warranty right? I would take it in.
September 26, 2009It still is under warranty but I'm worried that they will hassle me because i do all my own oil changes. I'm thinking it might be better to wait until something actually happens to bring it in then have them give me problems and tell me i can't bring it in for anything relating to this problem again. But I think I'm going to buy one of those drain plugs with the magnetic tip.
October 1, 2009Thats not a bad idea. but still why wait for a problem? Yea dealerships are always a hassle but it should be a one time hassle to get the truck 100% and to me thats worth it. But its your call, just dont wait till its too late.
October 2, 2009i would take it in. if they give ya a hard time tell em" you think your the only ones that know how to change oil!"tell them hell i do it to get a second to my self...better that a bigger problem later..f um if they cant take a joke.
October 4, 2009I do my own oil changes too and there is no issue with that at the dealer - at least mine. It has never even come up. Just keep your receipts and a log and you are covered. It also sounds like you may want to look into an oil analysis. I use Blackstone Labs. Go to bobistheoilguy.com for all your oil info - warning though - it can be addictive.
October 4, 2009The word shavings makes me think long, thin pieces of metal. It is not uncommon to find very small particles of metal attached to the magnet, but "shavings" and 1/4 teaspoon of them, I wouldn't waste any time, I'd get that truck into the dealer.
October 7, 2009I guess i have to pay more attention to what I'm writing, I do mean tiny pieces not Shavings. I noticed them in the bottom of my drain pan, I don't have a magnetic tip drain plug. I would like to get one but the dealer says he couldn't find them for my truck, Just the non magnetic ones. Anyone go through this and get one someone else? My truck isn't anything special it's a 07, NNBS, 4.8. Thanks again for the replies, Justin
