Oil... Can I go from synthetic to non-synthetic?
 

With all the talk of Rotella vs. other brand oils this question came up offline. I am running Mobil 1 in my Z. I was under the impression that once you run synthetic it is not recommended you go back to non-synth. Can I do this?

Looking for opinions/advice. https://www.yenko.net/ubbthreads/imag...lins/dunno.gif

Re: Oil... Can I go from synthetic to non-synthetic?
 

I've switched to synthetic for easier winter starting and back to regular oil for summer with no problems. I believe that all oils are designed to be compatible unlike some antifreeze products.

Yes, you can switch from the superior performing synthetic oil to the lower performing dead dinosaur lube with no, "problems", other than reduced fuel economy, reduced performance, higher engine operating temperatures, harder winter starts, increased engine wear and higher maintenance costs. But, why would you even *want* to do this? https://www.yenko.net/ubbthreads/imag...lins/smile.gif

Hi Keith. https://www.yenko.net/ubbthreads/imag...lins/smile.gif Some other benefits of a good synthetic oil include reduced sludge build up/an internally cleaner engine, superior high temperature engine protection, improved performance, reduced engine wear, lower engine operating temperatures, improved fuel economy and still other benefits. If you want the best for your vehicle, I'd recommend using a good synthetic oil year round. https://www.yenko.net/ubbthreads/imag...lins/smile.gif

Darren, you'll be fine but why go back to regular Dino oil? A quality full Synthetic is far superior to anything that comes out of the ground. I've been using Amsoil and Mobil 1 in all my vehicles for years. My used oil analysis show that the stuff works.

The scoop seems to be that Rotella-T has the most zinc and other additives that are good for the engine. It seems that some of the other petroleum based oils removed some of these additives. Maybe because of the catalytic converters? https://www.yenko.net/ubbthreads/imag...lins/dunno.gif

With synthetic oil how often do you do oil changes

Hi Peter. https://www.yenko.net/ubbthreads/imag...lins/smile.gifThe vast majority of synthetic oils on the market only recommend standard drain intervals, i.e. the intervals recommended in the owners manual of a vehicle. Going further than what the oil manufacturer recommends can cause premature engine wear/damage. https://www.yenko.net/ubbthreads/imag...lins/frown.gif With AMSOIL Synthetic Motor Oil, recommended drain intervals are up to 35,000 miles. https://www.yenko.net/ubbthreads/imag...ins/3gears.gif You can visit my web site below for more information. https://www.yenko.net/ubbthreads/imag...iggthumpup.gif

Rotella-T is an oil formulated for diesel engines.

Is the standard oil filter used? https://www.yenko.net/ubbthreads/imag...lins/dunno.gif

Re: Oil... Can I go from synthetic to non-synthetic?
 

Yes, It is formulated for diesel engines but can be used for anything. The additives are important. I also believe with the old style engine assemblies (gaskets and so forth) they do have a tendency to find some leaks with the thinner synthetic oils on the street. Just an observation. I use Amsoil for my automatic trans, rear and transfer case on my pickup. Has 144,000 miles on it and never had a trans or rear problem. (changed every 50,000) I use conventional motor oil 10W40 and never had the motor apart, and never use an oil additive. Some engine builders recommend the Rotella because it still contains some of the additives that the other oils had but have since been removed. It may be important for the flat tappet cams, but not as much for the roller cams. So..... https://www.yenko.net/ubbthreads/imag...lins/dunno.gif

Re: Oil... Can I go from synthetic to non-synthetic?
 

Our COPO Chevelle went close to 200K miles the first time around on the regular oils of the day. The engine saw 7200 rpm a couple of times and more 6500s that I car to think about. When I tore the engine down the bearings still looked good and the pistons slid out of the bores without ridge reaming. The oil was changed regularly and most of the driving was highway. At 2000-3000 miles a year, I'll be dead and gone long before any of the engines in our old cars are worn out, no matter what oil we use. I use synthetic in our everyday cars due to the miles that we put on them. In the old ones I use synthetic in some but am not convinced that I need it. It can't hurt though. It's probably a little extra cheap insurance. https://www.yenko.net/ubbthreads/imag...lins/smile.gif

Correct Keith. NOT convinced that you need it. This debate will go on forever I bet. https://www.yenko.net/ubbthreads/imag...s/headbang.gif

Hello Bart. https://www.yenko.net/ubbthreads/imag...lins/smile.gif AMSOIL Ea Oil Filters have a recommended change interval of 25,000 miles or one year, whichever comes first. Best on the market. You can get more information at my web site below. If you don't find what you need, please feel free to e-mail me and I will help you out. By the way, AMSOIL products are made in the USA! No Middle East foreign crude! https://www.yenko.net/ubbthreads/imag...mlins/flag.gif

Hello Sam. https://www.yenko.net/ubbthreads/imag...lins/smile.gif You are correct, you don't, "need", a synthetic oil for your vehicles engine, (although with the Chevrolet Corvette, the engine warranty can be voided if petroleum oil is used). But, as with radial tires vs bias-ply tires, no we don't need better handling, braking, longer tread life, improved safety, etc., but it is very nice to have. We don't need fuel injection vs a carburetor for superior performance, longer engine life, reduced emissions and superior fuel economy, but again, it is nice to have. We don't need four wheel disc brakes vs drum brakes, for superior braking and better safety, but it is nice to have. Etc. https://www.yenko.net/ubbthreads/imag...lins/smile.gif

The benefits of a good synthetic oil vs a petroleum oil are many and include; superior power/throttle response, superior fuel economy, lower emissions, reduced maintenance/repair costs, reduced engine operating temperatures, less sludge/an internally cleaner engine, superior cold engine starting, superior high temperature engine protection, reduced wear/engine runs "like new" for a longer period of time and other benefits as well. My Yenko Camaro has had nothing but AMSOIL synthetic motor for almost twenty years and I wouldn't want anything less to protect that engine, not to mention the tranmission and rear axle. https://www.yenko.net/ubbthreads/imag...ins/3gears.gif Heck, my Yenko Camaro was how I discovered superior synthetic lubes like AMSOIL. https://www.yenko.net/ubbthreads/imag...lins/smile.gif

Re: Oil... Can I go from synthetic to non-synthetic?
 

I have always used Synthetic in my T/A and GN. I'm convinced the science supports the choice. But there are skeptics one of whom recently was brought over synthetics while installing a new MSD distributor in his Chevelle. The break in tag on the distributor warned against using synthetic oil during the distributor break-in period. A light went off in his head and now uses Mobil 1 in his car,..after he broke in the distributor gear using Valvoline dino oil.
