These finishes contain cobalt or manganese siccatives and who knows what else. I don’t consider commercial tung or linseed oil finishes food safe. How long/ how many miles has it been since the last one? If your answer is ‘I don’t know, get them both done asap, then after that keep track of the miles/ time until the next one, as recommended by your vehicle maker/ tire brand. Other hydrocarbons besides methane can be used as feedstock, but the yield and efficiency are best with methane. Carbon dioxide is the off-gas from the unit. I worked on one unit that was designed to produce reformate with a 104 research octane rating.Ī steam-methane reformer combines natural gas and steam to generate hydrogen for use in other catalytic processes. A by-product of the reaction is high-purity hydrogen that is used elsewhere in the refinery. Some straight-chain compounds are converted to cyclic (such as cyclohexane), and cyclic compounds are converted to aromatics (benzene, toluene, xylene). A catalytic reformer uses high temperatures and a platinum-based catalyst to convert low octane naphtha to high octane gasoline. Again operating under extreme conditions you could consider changing more regularly Shouldn’t normally need a flush if fluid is regularly changed. Also don’t neglect the transmission Change fluid and filter if applicable every 3 years 30,000 miles 50,000 kilometers or when it starts to look and smell dirty. Oil changes twice a year are pretty cheap insurance. I generally recommend full synthetic oil of the recommended viscosity and a quality brand name filter changed every 6 months or 6,000 miles to 10,000 kilometers. Lots of idling, short trips, and city driving or towing heavy loads or operating in severe conditions require more frequent changes. It does depend a lot on the type of driving that the vehicle is operated under.
