Can you use this product and the anti-friction product at the same time?

Hello, and thank you for your question. We appreciate you considering Rislone for your automotive needs. Since you don't specify which anti-friction product you are asking about, it's difficult for us to give you a complete answer. What we can say is this: Rislone High Mileage Compression Repair (part number 4447) IS compatible with Rislone Nano Prime Engine & Oil Additive (part number 4104), which uses Nano Tungsten and Moly to reduce friction up to 38%. We have not tested the Compression Repair with products from other manufacturers, so we are not able to address possible compatibility concerns in that area. We hope this satisfactorily answers your question. If you have any other questions or would like additional information on these or any of our products, please feel free to call our Tech Support Team at 1-800-345-6572. We are here to assist you Monday through Friday, from 8 am to 5 pm Eastern time.

Can i use (mix) this product if i am using xl nanolube engine oil additive & nano treatment; reduces oil burning & engine smoke

Thank you for your question and for considering Rislone Compression Repair with Ring Seal (part number 4447) to help with your automotive needs. We cannot recommend these two products be mixed as we only have test data on compatibility within our own family of products. Since we don't test the efficacy or compatibility of our products alongside a competitors product, we can't advise you to use them together. We certainly appreciate your interest, but as a family run company for over 70 years, we pride ourselves on being honest with our customers - if we don't think we can help you, we will let you know, and in this case, we can't. If you have any other questions or we may provide additional information, please feel free to contact our Tech Support team at 1-800-345-6572. We are here to assist you Monday through Friday, from 8 am to 5 pm Eastern time.

Do i put in every oil chang or is it a 1 time and done

Every oil change. I have an 87 Toyota Corolla with 200k, it takes 3 at this point. I have observed that it works after the first trip. It has eliminated blue smoke and low oil pressure. "Your mileage may vary".
