Frequently Asked Questions

Our service is different than your typical oil change, so here's some questions we get a lot!

What brand oil and filter do you use?

For our AMSOIL synthetic packages, we obviously only use AMSOIL Signature Series oil. For our Conventional or Synthetic packages, we use a variety of different oil brands, all of which are API certified. If you upgrade to High Mileage, we only use Valvoline with MaxLife technology. Whether you pick one of our standard conventional or synthetic packages, or decide to upgrade to AMSOIL, you can rest assured either an OEM oil filter or quality name brand aftermarket oil filter is used.

What viscosity or weight of oil do you use?

Generally for liability and warranty reasons we only use the OEM specified viscosity or weight of oil for your application. Where multiple viscosity grades are permitted by the vehicle manufactured, we'll use our experience, your vehicle mileage, local climate, and specific usage conditions to determine the best oil for your vehicle.

Why are your oil changes a little more expensive than some other places?

Yes, you can find a cheaper oil change somewhere else - but we're different. First, we come to you, but don't charge any extra trip fees or service charges. Second, we use only quality oil and filters - no mystery oil out of a 55 gallon drum or generic cheapo filters! Third, we don't perform additional services or upsell you on things like air filters or wiper blades, which is how most places make money on loss-leader priced oil changes. With OnSiteOilChanges.Net, you know exactly what you'll get, and how much you'll pay.
