The Challenge
Running subscriptions across a large automotive catalog isn’t like running a supplement program or a coffee subscription. Replenishment timing varies by driving style: a long-haul trucker burns through fuel filters on a completely different cadence than a weekend driver. A fleet operator knows their schedule; a daily commuter doesn’t. Getting cadence right for every customer requires current, reliable, actionable data the team can actually find.
On their previous subscription platform, that visibility wasn’t there. The analytics weren’t straightforward. There was no easy way to see what the program was doing day-to-day, let alone use that information to act. With a catalog growing in both SKU count and subscription complexity, Doc’s Diesel needed a platform that could keep pace and show its work.
The Solution
1. Complicated onboarding? Not with Stay AI.
- What was done: Doc’s Diesel migrated their entire subscription program to Stay AI, including over 2,500 active SKUs. The Stay team led the onboarding end-to-end , configuring selling plans, validating the catalog, and making sure the transition didn’t disrupt subscribers.
- Why it mattered: At this catalog size, migration risk is real. Product-to-selling-plan mapping, subscriber data integrity, and timing all need to be right. An error at launch means disruption at scale.
- Proof: The transition was smooth enough that Bunnie Aprahamian, Doc’s Diesel’s Head of Ecom, called the setup process and support great and says the program’s trajectory was apparent almost immediately after going live.
“The setup process was smooth from day one. The Stay team was with us the whole time and super helpful. And once we were live, the data made it clear immediately that this was the right move.”

2. Replaced guesswork with analytics that the team checks daily.
- What was done: Stay AI’s analytics dashboard became Doc’s Diesel’s primary subscription intelligence surface. Bunnie opens it and refreshes it every morning, and built her own year-over-year comparison across the same seasonal window to benchmark what the program was actually doing pre- and post-migration.
- Why it mattered: Subscription programs without live analytics are managed on instinct. On their previous platform, pulling meaningful data was complicated. With Stay AI, core metrics, churn, AOV, subscriber growth, and orders are visible by default, and the new additional reporting gave the team granularity they hadn’t had before.
- Proof: In the year-over-year comparison, Doc’s Diesel tracked a 220% increase in monthly subscriber reactivations.
“I have the Stay AI dashboards open every single morning. I’m not exaggerating; I refresh first thing. The visibility is completely different from what we had before. Now I can actually see what the program is doing and where to focus.”

3. Cut churn with Stay’s advanced retention tools
- What was done: Doc’s Diesel used Stay AI’s retention tooling immediately after migrating. Their cancel flow copy matches the same plain-spoken, specific voice they use across all their marketing: direct about the problem, easy to act on.
- Why it mattered: A save offer only works if it speaks to why the subscriber is actually leaving. Generic discount prompts get ignored. Doc’s Diesel’s flows are built the same way they build everything else, from the subscriber’s perspective. In language that feels like it came from the brand, not a third-party app.
- Proof: Monthly churn rate dropped by over 5% year-over-year thanks to Stay AI’s retention tools.
4. Grew AOV by making it easy for subscribers to do more.
What was done: As Doc’s Diesel expanded their own branded product line, they needed to migrate existing subscribers off third-party SKUs and onto Doc’s Diesel equivalents across hundreds of products.
Rather than flooding subscribers with generic swap emails, they built segmented Klaviyo flows using Stay AI Quick Actions: swap links that route each subscriber directly to their specific replacement product, no portal login required.
Their Customer Portal carries the same voice; subscribers don’t
experience a tonal handoff between a Doc’s Diesel email and a Doc’s Diesel subscription page.
Why it mattered: Subscriber engagement reflects whether the experience feels cohesive. When a subscriber gets a swap email that sounds like Doc’s Diesel, clicks once, and their subscription is updated, that’s a program they trust and stay with. That trust compounds into higher order values over time.
Proof: Average subscription order value increased +15% year-over-year. Subscribers aren’t just renewing. They’re engaging.
“The moment we went live with Stay AI, the potential was obvious. Our churn rate came down, our AOV went up, and with tools like the Cancellation Survey, Customer Portal, and Quick Actions, now we have a complete subscription retention program. We’re just getting started.”
