My wife Linda and I are the current owners and caretakers of a C3 1980 Corvette. We like all Corvettes, but especially the C3 "Sharks," and most specifically, the '80-'82 body style. Our Corvette is equipped with its original and stock 280 lb/ft of torque, 190 horsepower, L48 engine option, coupled to its original Borg Warner Super T-10 4-speed manual transmission. Back in the '70s and early '80s, OEMs, to meet the EPA requirements, were engineering low emission, low compression ratio, unleaded gas engines. For 1980, the Corvette's L48 engine had a measly 8.2 compression ratio and was equipped with a so-non-Corvette 85 mph speedometer. Can you imagine, as compared to the current crop of C5, C6 and the new C7 Corvettes?
This is our second Corvette within 45 years of marriage; the first being a 1973 model year. We hold onto them and care for them for long periods. We are active Corvette hobbyists, members of the National Corvette Museum and the First State Corvette Club. Not our first Vette, but probably our last at our age.
We travel extensively with our 1980 Corvette: we attend and participate in various events of the Watkins Glen Vintage Grand Prix Festival (last four years in a row); travel to the Rockland, Maine, LobsterFest; to the Maggie Valley, N.C., "Vettes in the Valley Corvette Show"; to Bennington, Vt., for the fall foliage, and to Niagara Falls, Ontario. Our Vette is fully original and box stock; just as it came out of the St. Louis, Mo., GM Corvette plant on approximately Jan. 7, 1980.
And the "trunk" you ask? Okay, you didn't ask but surely you want to know as not many people see a Corvette pulling a "trailer". When we purchased this Corvette, my wife asked if it would have additional storage capacity as compared to our old '73. I told her it does, but "Honey, I've got that issue covered." The 1980 Corvette had a trailer-towing package option, ZN1. After conducting extensive research into motorcycle cargo trailers, we found this 25 cubic foot, adjustable air ride suspension trailer. The personalized license plate for the trailer...."Trunk."
So to get to the point, why do Mobil 1™ products make a difference to us? Well, for all our vehicles, but especially this Corvette, with its low torque and horsepower, flat tappet cam engine, our goal is to reduce power-draining parasitic losses, provide superior lubrication under additional load and stress, all while having sufficient zinc and phosphorous (ZDDP) for anti-wear. This means, for us, utilizing Mobil 1™ High Mileage motor oils, with a Mobil 1™ Extended Performance M1-302 oil filter. (For our Suburban and Tahoe, standard Mobil 1 synthetic oil is utilized, with the M1-206 oil filters.) Our Corvette, unfortunately, sits in an unheated garage for weeks at a time in between start-ups during the winter months, so the low temperature pour point as provided by Mobil 1 oil is mandatory.
Now, C3 Corvettes are known for their poor cooling. If you have ever driven in a C3 Corvette in the summer, well, GM Chevrolet Motor Division didn't have the best passenger compartment insulating materials back then. One of the reasons why current generation Corvettes are factory filled with Mobil 1 is because the engineers found that the engines ran cooler with Mobil 1, eliminating the need for an external engine oil cooler. In a C3 you sit with your legs and body next to the engine and transmission; believe us, a cooler running engine and transmission, even by a few degrees, is better. Speaking of the transmission and the rear differential (how did you like that segue?), we utilize Mobil 1™ Synthetic Gear Lube LS 75W-90. Again, we want to reduce power-robbing parasitic losses, wear and running temperatures, especially when pulling our trailer, which puts more stress on every component. Oh yes, we also utilize Mobil 1™ Synthetic Grease; albeit, we sure wish you distributed it in the smaller, hand-held grease gun tubes. Give that some thought, please.
Even though we are not the original owners and caretakers of this Corvette, knowing just a small amount of its maintenance history, we had no qualms about switching to and utilizing Mobil 1 products for it, as we use them for all our vehicles and motor equipment.
