Hi all...i just bought some arx to try out on my old datsun 240z...the engine in it is from a 79 280zx with 98k miles on it...so far it runs good with little to no oil consumption and has been well maintained but has a rear main seal leak that has goten worse since i tried some of that Valvoline High milage oil...so now im going to try some ARX and see how it goes...
Would a Zinc based oil be ok to use with ARX... i need to use a oil that has zinc in it and want to know if this will affect the ARX at all?
Thanks for the reply....I had Rotella in mind...reason being the old L series engines require a oil with ZDDP in it wich is being phased out of oils due to emissions...So i just wanted to know if a oil with zinc or adding a zink addative to the oil will affect the performance of the ARX at all...
The Rotella will be a fine oil to use with Auto-Rx, both on the clean and rinse cycles. If you are using this heavy duty Rotella oil, you should not need any extra zinc additives, because it already has a higher level of zinc/phosphorous than regular passenger car oils. Actually, all oils contain zinc/phoshorous in various amounts, but the diesel/gas rated oils like 15W-40 and 5W-40 synthetics like Rotella 5W-40 contain higher levels of the zinc AW additives that your engine needs.
I would avoid using any other additives while doing a Auto-Rx clean or rinse cycle, just to get the best results and avoid the possibility of competing chemistries that an additive may introduce.

Right...my main concern was if a oil with agood amount of zddp would hinder or compete against the ARX...so i guess it iwill be fine with it...
How does Castrol GTX compare? is there a oil analysis on this oil? I looked for one but couldnt find one....reason being i got some bottles that need to be used...
