Preheating Joe Gibbs break in oil to 180F

For me, no. There are a couple of companies, like JGR, that recommend this practice. Most other mfrs do not. I use Valvoline products, have not, do not, pre-heat the oil. People can get as anal as possible about stuff, but this seems like overkill. Besides, Valvoline is $4 / quart cheaper. $20 bucks buys a couple of filters.
