New LQ4 Swap?
Well not really new but new to me it has 50,000 miles. My question is what oil should i run in it. It has 5-30 on the oil cap. I was thinking of switching to mobil 1 5-30 but have heard before it isn't a good idea to switch to synthetic if you have been running dino oil for a long time. But i have no idea what was run in it before. I have a vortech sc so i also want whats best for it since it uses the trucks oil supply too.
Thanks

Sorry about the lack of details I have a 2000 extended cab 4X2 currently with a 5.3 gibson shorty headers (I wish they would of had Pacesetters back then for 300 bucks) BBk 80mm tb, flowmaster catback 3 inch back to muffler dual 2.5 straight out the back, k&n fipk, 42# injectors, Nelson tune, meth injection and a vortech running about 10#. I just bought a junkyard 6.0 liter to put in it b/c my 5.3 is burning oil like crazy and knocking. It's coming from cylinder # 7 so i checked the compression and on a good cylinder it was around 135 or so and on #7 it was only 65 So i got a pretty good deal on a 6 liter with 50,000 miles on it witch is about 49,000 less miles than my 5.3 had. I also have a transgo shift kit, tranny cooler, and a trailblazer converter to go in it at the same time with the 6 liter. I am going to make sure everything is perfect before running the 6 liter hard, i really don't know what happened to my 5.3 it ran really well with always less than 2* KR and this was in the dead heat of last summer. I was cruising down the interstate at about 80 when the check engine oil level light came on and i pulled over at the next autoparts store and it was 1.5 quarts low, and i could smell the oil burning ever since. It was all downhill from there. I'm going to leave the supercharger alone so 10# on a 5.3 will probably be about 8 on a 6 liter. I just want to do everything i can to make this 6 liter last as long as possible b/c this motors got to last me for a LOOONG time. I know what type of oil i was using had nothing to do with what happened but i just want to start out right with this new motor.
Thanks

Yeah i'm still trying to decide if a little over a hundred bucks is worth it. I will have the engine just sitting on a stand with the oil pan off so it will be an easy change. I might end up doing it just in case i decide to spin it higher and for peace of mind. How much of a drop in boost can i expect going from a 5.3 to the 6.0? I was thinking 2 pounds or so. I am hoping for a solid 8# with the 6.0.
Thanks for all the help guys
