Re: Mobil 1 oil
Jim S. I agree with you completely regarding Mobil’s attempts to mass market by reducing the additive package. I too was also told by one of our lubricating consultants that the additives are where the real cost is and Mobil has experimented to reduce in an attempt to get the price down. This is supported he said by the numerous versions/ formulas they have offered for Mobil-1 over the last 10 years; new improved, special formula, etc. He also stated at one time Corvette, Porsche, Ferrari was considering taking them off the recommended list but they reformulated back up to meet their requirements.
Based on our testing the best buy for racing oil presently is the Brad Penn, old Kendal stuff. It can be a little hard to get and they don’t have a wide offering of viscosities but dollar per ounce of lubrication it’s hard to beat.
If your oil works then don't change , however be aware that the formula my change over time in this highly compatative market so if you start having issues don't rule the oil out.
My 2 cents
