Sulfur is also reactive to Nikasil. Some cars in the eighties had Nikasil liners : Honda, Jaguar, Rover, and also Porsche. But the high sulfur content in the FUEL of that period did damage the Nikasil liners, thus causing severe loss of power and high oil consumption. The sulfur content of modern fuels is very low and it isn't harmful to Nikasil anymore. However, car manufacturers have changed to other production processes to reduce ring/liner friction, because of these problems but also because Nikasil is expensive for massproduction.</div><div>Marcel</div><hr id="zwchr" data-marker="__DIVIDER__"><div data-marker="__HEADERS__"><b>Van: </b>"van mulders marcel" <van.mulders.marcel@telenet.be><br><b>Aan: </b>"Russell Westfall" <rwestfall@ymail.com><br><b>Cc: </b>"fot" <fot@autox.team.net><br><b>Verzonden: </b>Woensdag 19 augustus 2020 23:41:31<br><b>Onderwerp: </b>Fwd: [Fot] Overdrive gearbox oil<br></div><div><br></div><div data-marker="__QUOTED_TEXT__"><div style="font-family:'verdana' , 'arial' , 'helvetica' , sans-serif;font-size:10pt;color:#000000"><br><br><hr id="zwchr"><div><b>Van: </b>"van mulders marcel" <van.mulders.marcel@telenet.be><br><b>Aan: </b>"Russell Westfall" <rwestfall@ymail.com><br><b>Verzonden: </b>Woensdag 19 augustus 2020 23:39:32<br><b>Onderwerp: </b>Re: [Fot] Overdrive gearbox oil<br></div><br><div><div style="font-family:'verdana' , 'arial' , 'helvetica' , sans-serif;font-size:10pt;color:#000000"><div>I believe most Triumph owners agree that engine oil can safely be used in the gearbox wether or not it has an overdrive.

Amici<div>I am running a TR4 with an overdrive. There seems to be several opinions on the proper lube to run in these transmissions. Is there a consensus on what works best in racing applications?</div><div>Russ Westfall<br><br><br><a href="https://overview.mail.yahoo.com/?.src=iOS" rel="nofollow noopener noreferrer nofollow noopener noreferrer nofollow noopener noreferrer" target="_blank">Sent from Yahoo Mail for iPhone</a><br></div>
