Diesel Oil Change in San Mateo, CA
CK-4 or OEM-spec diesel synthetic, OEM-equivalent or genuine OEM filter, DEF top-off, free inspection. Light-duty diesel oil change service — call to confirm we're set up for your specific platform before booking. From $129.
Diesel engines aren't gasoline engines. They run hotter, with higher compression, and produce more soot — which means oil that meets API CK-4 or OEM-specific specs. Different diesels want different specs: Ford Power Stroke (WSS-M2C171-F1), GM Duramax (Dexos 2), VW TDI (VW 507 00 low-SAPS for DPF), MB passenger diesels (MB 229.51 / 229.52 for OM642/651/656), Sprinter heavy-duty (MB 228.51). Beacon Auto Care in San Mateo stocks the right oil for your specific diesel and uses OEM-spec filters that handle the higher pressures.
Diesel oil-change scope — what we do here
Honest read: a two-bay independent shop isn't a diesel specialist. Where we're set up well: VW TDI (Jetta, Golf, Passat, Touareg), Mercedes passenger BlueTEC (GL/ML/E-Class diesel SUVs and sedans), Mercedes Sprinter for routine oil + filter service, and Ram EcoDiesel 3.0L. Light-duty diesel platforms where the procedure is "drain, fill with the right spec, change filter."
Heavier diesel work — full-DPF service, EGR cooler replacement on a Power Stroke, Duramax injector cup work, anything that gets into the emissions stack on the 1-ton trucks — we'll be honest if it's outside what makes sense for our shop and recommend a dedicated diesel shop. Call before booking on Ford Power Stroke 6.7L, GM Duramax 6.6L, or BMW diesels (X5d, 335d) so we can confirm what we can do in-house vs refer.
