Synthetic Oil Extra-Quart Cost: Dallas Menus Compared

Two Dallas-area service menus disclose what happens after five quarts. Park Cities Auto Care lists a full-synthetic oil change at $69.99 up to five quarts and an extra quart at $7.19; supplies and disposal are extra, with the observed coupon expiring October 31, 2026. All Star Auto Clinic lists full-synthetic service at $112 for four quarts, $124 for five, $135 for six, and $147 for seven. Park Cities’ oil menu and All Star’s service menu are comparable because both state quantity.

Quantity	Park Cities calculation	All Star menu
5 quarts	$69.99	$124
6 quarts	$69.99 + $7.19 = $77.18 before listed extras	$135
7 quarts	extra-quart rate beyond one is not stated	$147

The six-quart difference is $135 - $77.18 = $57.82 before Park Cities supplies/disposal and any tax. The menus use different package scopes and Park Cities’ coupon terms, so it is not a guaranteed savings claim.

Read the fine print with the dipstick

Give the shop year, engine, oil grade, and capacity. Park Cities limits grades and says supplies/disposal are extra. All Star’s displayed menu does not establish whether its six-quart line includes the same filter or inspection scope. Ask for filter, oil specification, disposal, and tax on the estimate.

For a six-quart vehicle, the five-quart headline is incomplete. Use the disclosed $7.19 extra-quart rate only for the Park Cities package and use All Star’s six-quart line only as its own package price. Recheck the Park Cities coupon after October 31, 2026 and save the current menu before booking.
