What’s the best full synthetic performance engine oil? I know everyone has there own opinion. Looking for good anti-wear with high ZDDP zinc content. I currently am using Penngrade 1 (Brad penn) 15w40 and a couple bottles of Lucas ZDDP additive, but when the truck comes out of storage the oil is being changed and wanted to know if I should stick with it or switch brands. Truck is a 2006 Dodge Ram 2500 with a long rod 6.4L around 1000hp daily driven and rode pretty hard, with occasional track use. I am using a Hubb Billet reusable filter with oil change intervals between 1500-3000 miles depending on if I race it or not. Price doesn’t matter, and I don’t test my oil so anybody that has tested oil please chime in. Was thinking about a switch to Cenpco but wanted other opinions on what everyone is using. The penn grade 1 I can get from my local NAPA.
