How, exactly, do you formulate an oil for an older engine (besides adding lots of ZDDP for flat tappet cams)? Except for (possibly) looser clearances--not necessarily so if you have a good machinist--what is the difference between an older iron block and a newer one (I know many modern engines are Al), Al pistons, steel con rods, babbitt bearings, etc. <br><br>We are running modern oils in:<br><br>- a 1946 Chevy 2-ton truck<br>- a 1955 T-Bird<br>- a 1956 BN2/100M<br>- a 1965 Mustang (289)<br>- a 1967 BJ8 (that gets 4-5K miles/year and uses--drips, mostly--a quart of oil every 3,500 miles)<br><br>... with no issues with the oil whatsoever. Sorry, but while I'm sure Pennrite is a good oil, unless you/they can tell me exactly what needs to be formulated for older engines it sounds like marketing blather to me. If 'formulated for older engines' means you get lots of sludge and gunk in the pan thanks, but I'll pass. I had the timing cover off my BJ8 to replace the seal the other day and was astounded at how clean it was; not a speck of crud (110,000 miles since the last rebuild).<br><br>Note there are strict requirements (per SAE) for oil viscosities, so 20W-50 Pennrite is the same viscosity as 20W-50 KMart oil and, BTW, there's no good reason not to use a multi-vis oil; you're doing your top end a disservice every time you start the engine if you don't. I believe Pennrite makes a XXW-60 oil, which should give a little more oil pressure if your engine is oil pressure-challenged.<br><br>Any racers on the List care to chime in? Richard M., aka 'Boy Racer,' are you on here?<br><br>Gearboxes? No question, modern synthetics--like Redline MT-90--are hands down the best (if you can live with the leaking--I can).<br><br>Bob<br><br>ps. I'm not trying to be antagonistic Patrick, I just don't buy the Pennrite line<br><br><o:p></o:p></p><div><p class=MsoNormal>On 6/10/2015 5:53 PM, Patrick & Caroline Quinn wrote:<o:p></o:p></p></div><blockquote style='margin-top:5.0pt;margin-bottom:5.0pt'><p class=MsoNormal><span style='font-size:10.0pt;color:windowtext'>G’day</span><o:p></o:p></p><p class=MsoNormal><span style='font-size:10.0pt;color:windowtext'> </span><o:p></o:p></p><p class=MsoNormal><span style='font-size:10.0pt;color:windowtext'>I don’t think you read was I said.</span><o:p></o:p></p><p class=MsoNormal><span style='font-size:10.0pt;color:windowtext'> </span><o:p></o:p></p><p class=MsoNormal><span style='font-size:10.0pt;color:windowtext'>Not a problem using modern oils, but they should be oils formulated for older engines.</span><o:p></o:p></p><p class=MsoNormal><span style='font-size:10.0pt;color:windowtext'> </span><o:p></o:p></p><p class=MsoNormal><span style='font-size:10.0pt;color:windowtext'>Take for instance the oil for the gearbox.
