SAE 10W-30 sits next to 5W-30 as one of the standard multigrade viscosities on our shelf, and American Oil Wholesale and Distribution stocks it across sixteen brands, from Thunder value cases to Mobil 1 full synthetic, plus two lines branded specifically for diesel engines. One wholesale account at our Hialeah warehouse covers the full range, so a shop running both a gas bay and a diesel bay can order every 10W-30 SKU on one invoice.
This guide lists every 10W-30 product we carry, tier by tier, with pack sizes and a plain note on which lines are gasoline formulations and which carry diesel branding, so auto shop owners and fleet buyers can order the right one.
What the 10W-30 Designation Means
The two numbers in "10W-30" are independent limits set by SAE International's SAE J300 engine oil viscosity classification, the standard the industry uses to define multigrade oil (SAE International, SAE J300). The "10W" is the winter rating: it caps cold-cranking viscosity, a step thicker at cold start than the "5W" rating on our 5W-30 lineup. The "30" is the same high-temperature rating carried by any other 30-grade oil: a kinematic viscosity window of roughly 9.3 to under 12.5 mm²/s at 100°C once the engine reaches operating temperature. The winter number and the hot number are set independently, so a 10W-30 and a 5W-30 from the same product line perform identically once the engine is warm and differ only in cold-start thickness.
House Brand Tier: Thunder and American Oil
Thunder, our value workhorse brand, covers 10W-30 from conventional through full synthetic in the same 12/1-quart case format. American Oil, our private-label house line, skips the case and ships 10W-30 by the 55-gallon drum and 275-gallon tote.

Two Diesel-Branded 10W-30 Products: What's Different
Two lines in our 10W-30 catalog carry diesel branding instead of a passenger-car label: Shell Rotella T4 Conventional Motor Oil SAE 10W-30 and Motorcraft Super Duty Diesel Motor Oil SAE 10W-30. Both ship in case format only, and neither one lists a specific API diesel service category, such as CK-4, on its current catalog entry. Treat them as a lighter-viscosity option inside each brand's diesel-branded family, and confirm the current certification and the equipment's OEM interval with your sales rep before specifying either one for a diesel service job.
| Product | Pack Sizes | Note |
|---|---|---|
| Shell Rotella T4 Conventional Motor Oil SAE 10W-30 | 3/1 Gal | Diesel-branded line; confirm certification before a spec-sensitive job |
| Motorcraft Super Duty Diesel Motor Oil SAE 10W-30 | 12/1 Qt, 3/5 Qt | Diesel-branded line; confirm certification before a spec-sensitive job |
Value and Specialty Tier: TekStar, Xcel, CAM2, and Duramax
TekStar spans the full range from a standard formula through ILSAC GF-6 synthetic blend and full synthetic, all three available by the drum and tote. Xcel, CAM2, and Duramax round out the shelf.
| Product | Formulation | Pack Sizes | Best For |
|---|---|---|---|
| TekStar Auto Motor Oil SAE 10W-30 | Standard formula | 12/1 Qt, 55 Gal, 275 Gal | Lowest entry price point |
| TekStar Syn-Blend GF-6 Motor Oil SAE 10W-30 | Synthetic Blend, ILSAC GF-6 | 12/1 Qt, 55 Gal, 275 Gal | Current ILSAC GF-6 spec |
| TekStar Full Synthetic Motor Oil SAE 10W-30 | Full Synthetic | 12/1 Qt, 55 Gal, 275 Gal | Value full synthetic |
| Xcel Premium Motor Oil SAE 10W-30 | Standard formula | 12/1 Qt | Sharpest price point |
| CAM2 Synthetic Blend Super/Pro Max Motor Oil SAE 10W-30 | Synthetic Blend | 12/1 Qt, 55 Gal, 275 Gal | Value blend, case-to-drum |

Buying 10W-30 Wholesale, by the Case, Drum, or Tote
Every SKU on this page ships from our Hialeah warehouse on the same invoice as the rest of your fluid order: coolant, ATF, DEF, gear oil, and brake fluid. Auto shops across Miami-Dade get next-day delivery, and Broward and Palm Beach ride the next scheduled route day. The $250 domestic minimum is easy to clear once a 10W-30 order rides with the rest of your fluids, and C.O.D. terms let a new account start simple.
If your ticket mix skews toward high-volume service work, the American Oil, Prime Guard, Super S, Mobil, Chevron, Castrol, TekStar, and CAM2 drum and tote formats let you pump 10W-30 directly instead of breaking case after case. A single 275-gallon tote holds roughly the same volume as 55 five-gallon pails, so a shop running steady 10W-30 volume receives and stores one unit instead of dozens of smaller ones.
Stock the Grade, Confirm the Application
10W-30 covers passenger-car formulations from entry-level to full synthetic, plus two diesel-branded lines that belong on a different shelf. Request a wholesale quote to confirm current availability by formulation and pack size, and add it to the same account as the rest of your fluid program.
