Recently bought a used boat with a 5.0 Volvo engine that has been winterized and I’m not sure which additive the prior owner used. Can I add your product to the existing product and be safe? I typically use your regular Sea Foam treatment. Thanks.

Hi Charles,
Yes, Sea Foam and/or Marine PRO can be safely combined with other stabilizers. Both Sea Foam products are made from 100% petroleum ingredients, so it won’t cause problems when added to fuel containing other treatments.
