Buying guide and frequently asked questions
How to choose
Choose the exact product and dose for your fuel and equipment. Fuel additives do not replace two-stroke oil, engine oil or mechanical repairs. Neutra’s diesel-vehicle applications are restricted to older vehicles in the manufacturer sheet; modern diesel treatment belongs in the diesel category.
Can I use the same dose for both products?
No. Concentration and application differ. Follow the specific container label and technical sheet for the amount of fuel you are treating.
Are prices per bottle or per case?
Prices apply to the selected package. A 12-quart case contains twelve 1-quart bottles; other packages are labeled separately. Review the package selector on the product page.
Eligible standard orders over $300 ship free to one address in the lower 48 states; orders of $300 or less have a $75 shipping charge. Freight exclusions apply. See our shipping page for pails, bulk packages and quote requirements.
