I will do a oil flush next time before changing it but my xr6t is still clean inside and both cars have the same km's on the clock.I did assume though that the oil in my territory had done alot more km's than the previous owner mentioned!

nelsonian101 Donating Members 961 Member For: 16y 5m 4d Gender: Male Location: Sydney Posted 09/01/13 11:00 PM Share Posted 09/01/13 11:00 PM Have been using Royal purple 10w 40 since 7,500kms. My FG has now done 187,500kms! Must be a record! Also done at least 20 full circuit days and it gets flogged, trust me. Can't fault the oil but it does get get changed every 7,500kms (before circuit days) and who on this forum doesn't throw money away on these cars? The higher end synthetics are all much the same. Penrite, Amsoil and Mainlube all good. There a plenty of threads anwering why not to use a 0W though. Link to comment Share on other sites More sharing options...

Impellor Member 835 Member For: 14y 4m 9d Gender: Not Telling Posted 09/01/13 11:30 PM Share Posted 09/01/13 11:30 PM (edited) Sorry Ralphie looks like they are keeping it a secret. I also use Penrite. But what I have uncovered is that they RP and Penrite have similar flash points, and are using zinc not sulphur as friction modifiers. I know Penrite used high quality base oils, so I'd suggest the greatest difference in the two oils is price.Cheers Edited 09/01/13 11:33 PM by Impellor Link to comment Share on other sites More sharing options...
