AMSOIL Dealer Synthetic Oil Inc San Diego — AMSOIL Dealer – Synthetic Oil Inc is an authorized independent AMSOIL dealer based at 2587 Moonstone Dr in San Diego’s Serra Mesa neighborhood.

About Synthetic Oil Inc
AMSOIL pioneered extended-drain synthetic motor oil formulations nearly fifty years ago; independent dealers like Synthetic Oil Inc extend that catalog to consumers who prefer phone or web ordering with technical guidance rather than big-box retail aisles. Public site copy positions the San Diego operation as a nationwide authorized dealer leveraging ten AMSOIL wholesale warehouse locations for fast shipping and competitive freight — including free shipping thresholds for Preferred Customer program members on qualifying orders.
Southern California driving conditions — coastal humidity, inland desert heat, mountain towing across I-8 and I-15 corridors — create distinct lubrication demands. Synthetic Oil Inc markets localized maintenance recommendations through city-specific service area pages while fulfilling orders from the warehouse nearest each customer. The Moonstone Drive address functions as the dealer’s registered base in ZIP 92123 near Kearny Mesa auto row and Montgomery Field, though much of the business model is phone- and e-commerce-driven rather than walk-in retail.
Directory listings cite Monday–Friday business hours roughly nine to six Pacific; Saturday closure is common for independent dealer operations focused on shipping logistics. Confirm current hours before visiting for pickup or technical consultations.

Who they serve
Synthetic Oil Inc serves DIY motorists, independent repair shops, fleet operators, off-road enthusiasts, and marine owners nationwide — not solely San Diego County residents.

Customers who value extended drain intervals, racing-grade protection, or manufacturer-spec compliance for European imports often seek authorized dealers for SKU depth unavailable at general auto parts chains.

Frequently asked questions
Does Synthetic Oil Inc sell only to San Diego customers?
No. Public materials describe nationwide factory-direct shipping from AMSOIL warehouses across the United States. San Diego is the dealer’s home base, not a geographic service limit.
What is the difference between AMSOIL Signature Series and OE oils?
Signature Series targets maximum protection with extended drain intervals up to twenty-five thousand miles or one year where appropriate; OE aligns with original equipment manufacturer recommended intervals. A dealer can help match viscosity grade (e.g., 0W-20, 5W-30) to your owner’s manual.
Can local repair shops open commercial accounts?
AMSOIL offers installer and commercial account pathways referenced on synthetic-oil-inc.com. Shops receive pricing tiers and marketing support subject to program rules.
