Couple Maintenance Questions
Hey guys. I have a couple of questions. A few years back I owned an LS1 trans am, and have an extra set of spark plugs setting around for it. Would those fit in my 04 5.3 silverado?
Also, does anyone run Rotella in their gasser. My grandpa swears by it. I personally prefer Mobile 1. (this is more out of curiousity, I dont plan on switching oils).

I think they would fit however the 5.3L prefers AC delco Plugs.. Best bet is to see if they are the same part Via calling a parts store and double checking part numbers.
As for Rotella im not to sure to be honest. I know most of use use mobil, valvoline etc etc...Mike

Generally Diesel oils are higher viscosity like 15-40 or 20-50 weight, why would you need oil that thick? It will hurt your fuel milage. As far as your spark plugs go, Yes theroretically they will work but, your Trans am had a higher compression so the plugs are a little cooler in heat range to help fight off detenation, so for the realatively low cost for the correct plugs buy the ones that are an exact match.1999 Silverado Regular Cab Short Box

I think you can get rotella in the lower weight oils, plus if you have a tired older motor then the thicker oil will help. And the plugs i didnt even think about the compression ratio and heat. I only think about that on my sleds so thanks for reminding me as well joe........
