\NHITE3Y FREE PRESS,, Thursday, January 6t'h, 1972 , Page 9 MOTORING WITH Mîko Burgess ENGINE DII Since my Iast column on engine ail, a few more questions have been brought up p ert a ining ta ail calour, Bulk ail1, Castaroil andadditives which I wvill try ta caver in this article. Exper t s \warn that the lubricating quality of a matar ail cannot be judged by itscalour after it has been in use for evenonlyashort time. Dispersants and i n h ibitars added ta present-day mator ails, tend ta, change its côour once the ail i s put ta wark and subjected ta en- gine heat. Sa don't be alarmed if yaur ail 1turns black shortly after an oil change. BuIk Ois Reconditianed ai-ls, commonly cal- l ed 1 BuIk ails' are generally not rec- ammended for use in gaad engines. These ails are made up from a mixture af ails (some. ;mes used ails), fil tered, with ad- ditivesadded. Thisisa tricky pracess, and usually results in these ails being soldwvithout any guaranteeof quality or perfarmance standards. Castor 011 Castor ail, avegetable ail stili used by some enthusiasts, w1as once usedvery s uc c essful lyin racing cars.1it gives good lubrication, and gives off a nice e xh a ust odour, but al though having a good viscosity index, it becomes cor- rosiveveryquickly. So unless you like changing the ail every fewhundred miles 1 waouldn't recommend it. Additives basically make an ail inta amulti-gradeoil by increasing the vis- c o sity. Besides the fact that some ad- di tives are not necessari ly compatible with the ail being used, praperly oper- ating engines shouldn't need them anv- wa y. An engineer at a major ail1 cam- p an y t old me that if his campany's ail1 needeu anv more additives they wou!d have put them in, and the only reasan theymake and seilladditives is because ifpeaple are going ta buy them anyw,ýay, theymightaswell buy theirs! Suffice îi ta s ay that the use of additives shoul d generall1y be restr. icted ta extreme can- diî t ioans 1like racing cars or "iol burn- crsi". As p r evîousl1yment ianed 1 - 11aun- ces of dirt wllcampletely ruin an en- gine, sa abviauslv filtering is tremen- iýo us lv important.

If this is done, you wilI get ail p r e ssure right away and avoid the u s ual1 lubrication- starvation p e r i o d w h ich accurs while wai ting for the ail1 fil1ter ta f ili when the engine i s started. 1If this isn't done, which usually isn't, you wil11see the red ail1 pressure warn- ing light corne an, and stay an until the ail pressure isbuiltup. Anddespitewhat you may be told atherwvise, running an engine only withaut oil pressure even for only a short period, really doesn't help i t any.
