Does anyone have experience using KREX Graphite Lubricant specifically in the 6.6 Duramax engine? The GMC dealer I bought my 04' GMC 2500HD CC D/A adds this product as a standard during scheduled maintenance intervals @ 3K miles. The product is only available through new car dealer networks per the company data listed in the link below.
Before I add this to my truck, I'm trying to find information or maybe a user or two who can offer experience with this type of lubrication product.
