Re: What is the best oil for the beast.
I can't find that technical document I posted but its around somewhere.
The jist of the article was that Mobil 1 High Mileage was fine for the LT-5 engine. There are disadvantages to adding zinc if not done properly. I'm sure Valvoline and the others are good if you can find the 10W-30. I go with what has worked for me. I have had several engines well over 100,000 that ran like a raped ape and they were clean as a whistle. Mobil 1 works for me. I buy it often for $19.99 to $25.00 for 5 quarts. I buy a ton of it for the 3 Corvettes and Mobil 1 has a rewards program. I change my oil seasonal regardless of mileage. Many times I change it prematurely at 3,000 miles. If I get busy, then higher mileage. On my Z - its really spoiled. Often times, it only has a few hundred miles on the oil. It gets seasonal changes, especially after the winter storage if I'm in a cold state. My oil cooler oil stays in good shape as a result. It is way overkill but my oil changes are dirt cheap since I always get the oil on sale and do it myself. If memory serves me right, regular mobil 1 is good for 6 months and extended mobil is good for 1 year. (as long as within mileage limitations) I also do my coolant now at 1 year intervals.
