DuroStar DS4850EH 3850W/4850W Dual Fuel Electric Start Generator New

First , a quality paint-job and smoothed edges throughout . An attractive unit . But be forewarned ; the bolts through the metal shipping angle into the frame were extremely tight -- unnecessarily so . Penetrating oil was needed to finally loosen them .
After doing the wheels and legs assembly , I added exactly 20 fluid ounces of 10-30 oil and ran it on propane for the five hours of break-in while varying the loads from 600 watts up to about half-capacity 1500 watts . A quick full choke gave an instant start . It used no oil during the above hours and was not much blackened when drained and changed afterwards . Running noise level was a bit higher than expected ; earmuffs being recommended when starting and working close-by . Moving it around using the handles is done easily . Very few generator brands this size produce a 120/240 volt capability , so that's why this brand was chosen and is recommended if you ever might need a 240 volt capability . My residence standby system is an 8000/10000 unit plus this DS4850EH , this latter one to drive a well pump and the refrigerator and night lights overnight . Both units are fed by a 500 gallon propane tank . All issues pondered and considered , this is a very desirable and inexpensive midsized generator . At the price , I should have bought two of them .
