Hi, I am new to the forum and would like your thoughts on an oil selection. I use the same oil for both of my vehicles. I am looking at moving away from Amsoil. Their oil is getting costly, and I don't know if the price is justified (my last purchase averaged $7.21 a quart). Their MLM tactics have started to bug me, and I wonder if the market will bare these practices in the future. I have looked at Walmart and Penzoil Platinum caught my eye. Would this be a good replacement oil, or is there another that I should consider for my particular scenario? Also I saw the FRAM ultra synthetic filters. I picked one up for the Ranger, but might switch to these filters. Do they offer the increased performance to justify the additional cost. They are definitely heavier. My experience with petroleum filtration has me thinking that they may be better constructed with additional filter media. I thank you for any input that you can give me. Thanks!
