BRAD PENN® PENN-GRADE 1® "Nitro" 70 High Performance Oil High viscosity, high-performance motor oil engineered for use in nitromethane or methanol fueled competition engines. The heavy viscosity and exceptional film strength provided by the Penn Grade™ base oils helps protect against cylinder ‘wash down’ and oil ‘thinning’ from fuel dilution typically encountered in these applications. NOTE: Shipping oil can be expensive. Shipping 2 cases at once is only a bit more expensive, and lowers the shipping costs per case significantly! |
