okay,the question is this.if you needed some diesel oil and you went to your favorite parts store and all the non syn hdeo was on sale for 9.99.without thinking.what would automatically be your 1st choice.i'm just curious what most people would gravitate to.the choices would be castrol brand,rotella,delo,delvac or no name generic brand.this question isn't about what application it's being used for,or how many miles it will be used for.just a simlpe hey?...thats a good price and i'm gonna stock up type of question.thanks for your replys!!!
