I'd like to try either the Rotella-T6 or Chevron Delo 400 synthetic 5w40 in my Detroit during the coldest months of Winter, but I've used nothing but Delvac Super and Delvac Elite, and had really good results with both. My concern is switching brands may result in additive clash.
Is additive clash a real concern or an old wives tale?
Truck stop is the last place to buy any oil. Their prices are criminal, even for conventional oils.
Absolutely, Tired Trhcker. I buy my gallon jugs for topping off at Walmart. And as most other Truckers, I stock up on the road for everything else at Walmart.
T6 and Delo 400 synthetic is priced roughly $8 to $10 dollars more per gallon jug than conventional at Walmart. Figure we have close to a 10 gallon capacity in our motors, the added cost adds up. I don't ever see the semi-synthetic Mobil Elite 10w30 stocked at Walmart, but they do stock the T5 and Delo 400 10w30 semi-synthetic oils. I called my local Mobil Distributor in Salt Lake City for the price on gallon jugs of Delvac Elite 10w30, and their price was barely cheaper than the over-inflated Truck Stop price, so I'll keep looking.
Seeing as we run the same motors, when you changed over to Schaeffer's, did you notice an increase in consumption at first? Is "Additive Clash" when switching brands truly a concern?
Thank you.
