consensus on rotella t

I haven't figured out this acid thing yet. I had learned that it was bad to put an engine away with old oil in it and it was best to change oil before storage. In 1962 I purchased a 1926 Buick Master that had been in a garage since 1936 according to the license plate on the car. When I started the engine, the valve springs broke and almost half of them needed to be replace. At that point, I took down the oil pan to clean out the sludge at the bottom, and pulled off a couple of the connecting rod caps to inspect the bearings. There was no pitting or wear on them. The same for the main bearings that I inspected. Considering that the engine had the same old oil in it for 26 years without any thing being done to it, leads me to believe that the acid problem in engine oils is greatly exaggerated, along with a lot of other myths about oil. I often wonder how engines survived with out these fancy oil filters and synthetic oils... /forums/images/graemlins/wink.gif

hmm. acid "greatly exaggerated", that is why some oils when using in acidic engine oils, their TBN drops like a rock and there OXD, and NOX levels shoot up....

It is not a myth, but happen. Most time people using dino change oil sooooooo fast, that they do not see it or know about it. Will dino work sure, but then again so did a horse and plow...It is called progress.

Synthetic oils are not liked by most people since it comes down to 2 things and 2 only;
#1 price is too high
#2 miss information/not educated enough

The original engine out of my '62 Biscayne is sitting on a shelf in my barn (I replaced it with a 502ci big block - told the wife it needed a bit more oomph) and it does not even have an oil filter on it; it never has. According to the original window sticker I have and the order sheet, not only was an oil filter "optional", but so were seatbelts! /forums/images/graemlins/shocked.gif The ole' in line 235 six cylinder still purrs like a kitten sans oil filter. However, I do think that some of the "new technology" is a good thing. I will likely be putting this old 235 in another "project" and, in an attempt to make sure it continues to purr like a kitten, I'll more than likely add an "optional" oil filter and use a very high grade synthetic oil.

I've switched both of my diesel tractors over to Rotella Syn 5W40. When I run out of Mobil1, (10 cases), I'll be switching over the daily drivers as well. On the cars I do oil analysis to set the oil change interval. On the tractors I change the oil once a year, which is under 100 hours for both tractors.

( not only was an oil filter "optional", b )

Same with my old fords.. many tractors of that era had no oil filter.. the forn N was 'advanced' due to it's 'partial' flow filter design. Even then, there was no hydro filter though.

I think the point gsxr made about acid not becoming an issue due to the frequent oil changes is particularly contentious concerning the marketing of synthetic oils. In other words.. dino oils are running almost as well if you follow the recomended changes. Thus.. sticking to that.. if you follow recomended changes.. the benefits of a synthetic are greatly reduced compaired to a dino oil.. when looking at acid #'s. I realize there will still be some superior lubricity, cold pour point, and film tension.. etc.. but we are talking acid right now..

( but we are talking acid right now.. )

I had to put on my glasses. I thought you'd typed that "we are taking acid right now..."! /forums/images/graemlins/shocked.gif And to think, I thought we were talking about motor oil! /forums/images/graemlins/blush.gif /forums/images/graemlins/grin.gif

Your talking about acid and I think that some of the participants are taking acid. I am still waiting for the answer as to what oil to use in my air cooled engine. Remember it is a turbo... /forums/images/graemlins/grin.gif /forums/images/graemlins/grin.gif Quick... hide the acid.... Bird is coming.. /forums/images/graemlins/blush.gif

LOL, why bother using the internet to talk about dino oils when you could simply use a telegraph and reserve the use of the internet to talk about synthetics? /forums/images/graemlins/wink.gif

May I try and catch up? What is dino oil? Sound guy I use Rotella syn and I like it but I change often. Mike I deliver mail for a living, in my own vehicle, I run this mobile one syn 10w 30 year round. I change every eight thousand miles and I get mighty good service out of it but do you have any suggestions. Do I need to do a sample to see if I am changing more than neccessary or not enough. I respect your thinking. I am not a professional in the oil stuff but like to learn the best for my things. Mail delivery is tough on oil I am sure, the temps of stop and go.....luck be yours teddy
