Star Tron Concentrated Diesel Fuel Treatment in the 8 oz size gives you one 8 US fl oz container for a planned diesel maintenance routine. This listing is SKU 113258, MPN 93108. This bottle is an option for a compact diesel maintenance kit or for an owner who prefers a smaller additive container. Check the diesel formula code before buying: an 8 oz gasoline bottle and an 8 oz diesel bottle do not share the same treatment rate.
This 931-series product is the concentrated diesel formulation. Manufacturer guidance describes its use for diesel fuel-system care and stabilization. Choosing the diesel formula avoids confusion with the similarly named gasoline and classic diesel products, which have their own application rates. Keep that formula distinction visible when several types of equipment are maintained together.
At the published rate of 1 US fl oz per 32 US gallons of diesel, the 8 US fl oz package supplies 256 US gallons of calculated standard treatment coverage. This calculation describes the amount of fuel that can be treated over measured applications. It does not mean the whole container should be added to a small tank, and it does not establish a separate initial or remedial dose.
Add the measured diesel treatment before refueling as directed, using the actual fuel amount for the calculation. Use suitable dispensing equipment and keep the container clearly identified. Where a tank has a known contamination problem or an engine continues to run poorly, arrange inspection and appropriate service. Package size should support your maintenance schedule without replacing careful measurement or equipment-specific fuel requirements.

Frequently Asked Questions
What does SKU 113258 include?
This listing includes one 8 US fl oz container. The store-listed code is 93108.
Which fuel is this product selected for?
This is the 931-series concentrated diesel formula. Confirm the delivered label and the equipment requirements for your diesel application.
What is the standard diesel treatment rate?
The published standard rate is 1 US fl oz per 32 US gallons of diesel. Check the exact label for any additional first-use or special-treatment directions.
How much fuel does this package treat?
Calculated at the standard rate, one 8 US fl oz container covers 256 US gallons. Coverage can be spread across separately measured applications and is not an instruction to empty the container into one tank.
Does a larger package change the concentration?
Package size and concentration are separate choices. Compare the exact formula code and label rate before substituting a differently named product or bottle. A larger supply does not justify a larger dose for the same fuel volume.
When should I add this fuel treatment?
Manufacturer directions say to add the measured product just before each diesel fill-up. Follow the exact container instructions for your formula.
Can fuel treatment replace an engine service?
An additive is part of fuel care. Persistent operating problems or uncertain fuel condition need inspection and appropriate service. Follow the equipment manufacturer’s maintenance requirements.
How can I confirm this package before ordering?
Contact Mariners Warehouse with SKU 113258, code 93108, the fuel type and fuel volume. Confirm the purchase quantity and formula before completing the order.
