I just got my ARX today and I am going to do a treatment on my Nissan Altima 03 V6 with about 84K miles this weekend. I'm the original owner always used synthetic oil M1 than switch to Amsoil till now. Is this safe for me to do a treatment with a conventional oil for 2.5 to 3K miles and switch back to Amsoil? I need your help. Thanks.
Auto-Rx® works with generally the least expensive motor oil available. Conventional engine oils include Valvoline Conventional, SuperTech (available at Wal-Mart), and Coastal (available at AutoZone).
Group III Oil,s which include Pennzoil Platinum, Castrol Syntec, and Valvoline Synpower work well also
Use of high-mileage engine oils should be avoided during all Clean and Rinse Phases. However, high-mileage engine oils can be used while following an Auto-Rx® maintenance plan.
If your engine has a supercharger, turbocharger or the manufacturer recommends that you only use synthetic motor oil please choose a Group III motor oil to avoid competing chemistry
Always choose the engine oil weight (viscosity) that your engines manufacturer recommends.
