On Site Mobile Lube, LLC can get you just about any type of fluid you may want for your vehicles' maintenance. That being said, we generally use Shell lubricants because they meet just about all manufacturer specifications, many different weights and variations are available, are reasonably priced, and are very affective.
Choosing the right oil for your vehicles' maintenance is really a matter of finding the right compromise. There are so many types of oils and lubricants available today and so many variations, weights and blends etc. to meet all the niche conditions. If money and availability are no object and only the best is desired, the choices can be greatly narrowed. Most fleet maintenance has very restricted cost boundaries though, so a compromise between price, availability, and performance must be achieved. The most important aspect, first, is to be sure the lubricant meets the vehicle manufacturer's required specification. Next the lubricants need to be changed at or sooner than the recommended intervals, depending on usage. Lastly, they need to fit the budget.
