I would ask the same dealer you bought the ELR about this problem. But changing the oil isn't hard to do. I remember that Valvoline had a chimp trained to do it, and yesterday I saw a article on TV of a eight year old girl who did it (you do see her in action!). The hardest parts are jacking the car up, removing the drain plug, draining the used oil, and removing the old filter. Then the easy parts are next: replacing the drain plug, mounting the new filter, releasing the jack, and adding the new oil. I have done hundreds of oil changes since 1967.
My 2009 Chevy Equinox has a tall ride height and floor clearance such that I change the oil and filter with no jacks, stands, or ramps. And the oil filter is vertical, so I never spill a drop of oil removing the old filter. I prefill the new filter with clean oil before mounting so the gas engine never starts up dry. Total cost for filter and Mobil 1 synthetic is less than $40.
