Brad Penn 1 is engineered with a higher ZDDP content, plus, unlike V1 racing, it has the necessary detergents and anti-corrosive properties and can be left in the car for more than 3 months or 1000 miles. I've run mine 2000 miles now in a 1976 Corvette 350/350 with almost no discernable discoloration of the Brad Penn 1. I pulled off the valve covers and there is a nice thin film of clear green oil, and no sludge, absolutely clean!!!! Love it. Buying it by the case, it's almost as cheap as a decent standard type oil. I don't know why people pay megabucks for Amsoil or Royal Purple, Brad Penn 1 is a hidden gem. No leaking either, so even though my seals are not the newest, this oil is staying put. I'll only be using this from now on, and will gladly run it in my 425HP solid flat tappet 351C-4V. ## Frequently Bought Together - PENN GRADE 1, 71446, Synthetic Blend High Performance Oil SAE 10W-40, 1 Quart (12 Pack) - WIX Filters - 51061R Spin-On Lube Filter, Pack of 1 - PENN GRADE 1, 71440, Synthetic Blend High Performance Oil SAE 10W-40, 5 Quart --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.sg/products/12944698-penn-grade-1-71446-synthetic-blend-high-performance-oil-sae](https://www.desertcart.sg/products/12944698-penn-grade-1-71446-synthetic-blend-high-performance-oil-sae) --- *Product available on Desertcart Singapore* *Store origin: SG* *Last updated: 2026-10-10*
