the fuel problem is a avery avery very cry real fact and und one with which we must reckon Motor vehicles land air and water ire are increasing ng with A far fa gi greater cater rapidity rap than is the fuel supply su supply sup sup- p- p ply an and there is no reason to hope that the time case casc will ever even be he different The only way we can keep the supply of fuel adequate t to meet our nee needs s is is by getting more mose work vork out of a given ghen amount of it For Ij or this reason the subject of devices for saving fuel is is a really realy important important important im im- on one and arId worthy of every cry car owners owner's consideration Most 1 lost of these devices have some merit and a few of them actually live up to their makers maker's claims for them I T Tam arn

class s of or fuel savers comprises what are re comm commonly nh known as h d J manifolds These two tale take a n number of forms forms but the tho prime prImo function la is s. s ys ys the tho same to Increase the explosive aluc value of or tho the fuel by feeding it in a warmed condition Into the tho combustion chambers The heated uses the manifold practically always l heat hoat o of tho the exhaust gases oases to heat the metal surface o of the th Intake manifold J so that the mixture In passing parsing over It I becomes thoroughly thI warmed through This Is Ig a n gr great at help holp

a n. type that thit pro provides provider cs for tho the thorough heating of oC taco t-io Some of these devices K do Jo not i to heat the mixture mixture mixture mix mix- ture thoroughly but merely to

In common us' us use There Thero are that employ emlo tho the heat of oC the exhaust and ethers others that depend on electricity but It Is hard to beat beit the well designed hc heated ted manifold In this c s may n na listed the so-called so hot hotspot hotspot spot that has his been popular during the past year or so flO Tho The hot spot Is la simply a heated area in the Intake manifold ove over which the ho fuel passes on Its way to the tho chamber gainIng a n certain amount of ot heat In the process There are arc on the tho market a number o of compounds of more or less mysterious ous OUR chemical analysis which are ar arf claimed to add tremendous power and mileage to tho the fuel Almost without exception th do se are aro fakes of or the worst sort I make e J however bo- bo c certain of oC these are sold b by re responsible responsible re- re people pp-ople who offer to refund the pu purchase price If It the buyer hujer is il not satisfied with results Naturally thorIs there thor Is 15 not much chance chanco to get stun stung on that kind l or a a. deal but in hi general I warn my nn readers to protect themselves from rom compounds of oC this varlet variety that I arc not guaranteed to give Ive the fhe results advertised J or r your our mone money back In In Its considering fuel saving devices we must take toko Into consideration the vaporizers which havo had a a. considerable consid consid- considerable erable vo vogue e for a year car or two past These Those Inject water vapor into the fuel mixture This treatment undoubtedly gives tho the fuel Cuel a little more moro en energy orgy because because be be- cause causo of or more complete combustion They fhe certainly tend ten to keep down the tha lon formation of or carbon and In general contribute something something- to the tho operation of ot the engine ensine This r Is type of or device that Is more popular for Ford use uso than on larger larg-er cars cars- Kerosene carburetors and other do- do e- e vices for tor permitting tho the use o of kerosene kerosene kerosene kero kero- sene as a fuel are arc worthy of oC consid consid- At the present time the price of oC Is not er very much belot below belo t that at o of gasoline but that will not al always always al- al ways WL'S bo be so But I must caution my readers to bo be very cr careful In installing a kerosene burning device because a poorly designed ono one Is a source of oC unendIng unending unending un un- ending trouble S Some me of or these bandie handle handlo han ban die dle the tho heavier fuel Cuci but they Induce such rapid carbonization that tho the owner is not repaid for putting them on In other ca cases cs the kerosene de deIce device device de- de vice Ice may do well wel enough with one en engine engine

rings Into tee oi of r reservoir reservoir res res- s- s where It quickly destroyed tho the lubricating qu quality p of the oil And still again I T have handled kerosene outfits that ts gave fairly r
