Oil Changes & Fluid Service

Heavy-duty oil and filter service using conventional or AMSOIL full synthetic, with a full under-truck look while it is on the rack.

What to expect

An oil change on a heavy truck is not a fifteen-minute upsell lane. It is the most regular look anyone gets under your equipment, and it is the cheapest opportunity in the whole maintenance cycle to catch something before it becomes a tow.

We run conventional and AMSOIL full synthetic. Synthetic costs more per service and stretches the interval, so which one is right depends on how you run — call and tell us the truck and the miles you put on it, and we will give you a straight answer rather than the more expensive one.

Straight Answers

Oil Changes & Fluid Service — common questions

How often should I change the oil in a semi?

As a general guide a semi runs roughly 25,000 miles between oil changes, but the honest answer is that it depends on the engine, the oil, the duty cycle and the manufacturer's schedule for your unit. A truck idling on short local runs is a different case from a highway tractor. Tell us how you run and we will set an interval that fits.

Is full synthetic worth it?

Often, but not always. Synthetic runs longer between services and holds up better under heat and heavy load, which suits high-mileage and hard-working trucks. If your unit does low annual miles you may not recover the cost. We stock both and we will tell you which one your truck actually justifies.

Can you do the oil change with my preventive maintenance or inspection?

Yes, and combining them is how most of our fleet customers run it. The truck is already on the rack and already down — doing the oil, the inspection and anything found in one visit costs you one day instead of three.

Where We Work

Oil Changes & Fluid Service across East County and San Diego County

The shop is on Riverside Drive in Lakeside, so the tow is short from most of East County — and a short tow is real money on a truck that will not roll. We take work from across San Diego County.
