Is it ok to change from normal oil to synthetic oil? My truck has about 130k on it and I live in winnipeg . Winnipeg has very cold winters. Is it also ok to switch back and forth to normal to synthetic. Thanks

It's perfectly OK to do that, but that constant switching between regular oil and synthetic might give your engine a tummy ache.
Why not select an appropriate blend, then alter the "weight" range of the oil for the expected contitions?

You might want to do some research on the issue first. When I switched from regular to synthetic a few years ago, my vehicle only had 10K miles on it. I remember reading high mileage vehicles required flushing the system first due to both oils being incompatable. I did all my research a few years ago and technology in oils may have changed.
Also they say you can go up the ladder (regular, semi, full synthetic) but you cannot go down.
Do your homework and be patient and get all the facts first.
Just my opinion!

There are no special requirements for switching from conventional petroleum to synthetic oil, ... however in older vehicles or those with very high mileage, it is advisable to use Engine Flush first. This will ensure that the engine is clean and free of any accumulated contaminants which might have an effect on the service life of Synthetic Motor Oils.
__________________________________________________
Let's put to bed some of the other objections you will hear concerning the use of synthetic engine lubricants (some are old debates ... some are new): ( Your concern is answered in Myth #4)
Myth #1: Synthetic motor oils damage seals
Untrue. It would be foolhardy for lubricant manufacturers to build a product that is incompatible with seals. The composition of seals presents problems that both petroleum oils and synthetics must overcome. Made from elastomers, seals are inherently difficult to standardize. Ultimately it is the additive mix in the oil that counts. Additives to control seal swell, shrinkage and hardening are required, whether it be a synthetic or petroleum product that is being produced.
Myth #2: Synthetics are too thin to stay in the engine
Untrue. In order for a lubricant to be classified in any SAE grade (10W-30, 10W-40, etc) it has to meet certain guidelines with regard to viscosity ("thickness"). For example, it makes no difference whether it is 10W-40 petroleum or 10W-40 synthetic, at -25 degrees centigrade (-13F) and 100 degrees centigrade (212 degrees F) that oil has to maintain a standardized viscosity or it can't be rated a 10W-40.
Myth #3: Synthetics cause cars to use more oil
Untrue. Synthetic motor oils are intended to use in mechanically sound engines, that is, engines that don't leak. In such engines oil consumption will actually be reduced. First, because of the lower volatility of synlubes. Second, because of the better sealing characteristics between piston rings and cylinder walls. And finally, because of the superior oxidation stability (i.e. resistance of synthetics against reacting with oxygen at high temperatures.)
Myth #4: Synthetic lubricants are not compatible with petroleum
Untrue. The synthesized hydrocarbons, polyalphaolefins, diesters and other materials that form the base stocks of high quality name brand synthetics are fully compatible with petroleum oils. In the old days, some companies used untested ingredients that were not compatible, causing quality synthetic lubricants to suffer a bad reputation. Fortunately, those days are long gone. Compatibility is something to keep in mind, however, whether using petroleum oils or synthetics. It is usually best to use the same oil for topping off that you have been running in the engine. That is, it is preferable to not mix your oils, even if it is Valvoline or Quaker State you are using. The reason is this: the functions of additives blended for specific characteristics can be offset when oils with different additive packages are put together. For optimal performance, it is better to use the same oil throughout.
Myth #5: Synthetic lubricants produce sludge
Untrue. In point of fact, synthetic motor oils are more sludge resistant than their petroleum counterparts, resisting the effects of high temperatures and oxidation. In the presence of high temperatures, two things happen. First, an oil's lighter ingredients boil off, making the oil thicker. Second, many of the complex chemicals found naturally in petroleum base stocks begin to react with each other, forming sludge, gums and varnishes. One result is a loss of fluidity at low temperatures, slowing the timely flow of oil to the engine for vital engine protection. Further negative effects of thickened oil include the restriction of oil flow to critical areas, greater wear and loss of fuel economy. Because of their higher flash points, and their ability to withstand evaporation loss and oxidation, synthetics are much more resistant to sludge development.
Myth #6: Synthetics can't be used with catalytic converters or oxygen sensors
Untrue. In fact the very low ash content of synthetics will extend the life of every exhaust system component.
Myth #7: Synthetics void warranties
Untrue. No major manufacturer of automobiles specifically bans the use of synthetic lubricants. In point of fact, increasing numbers of high performance cars are arriving on the showroom floors with synthetic motor oils as factory fill. Which may not make the dealers too happy since oil changes usually lead to other service work.
Myth #8: Synthetics last forever
Untrue. Although some experts feel that synthetic base stocks themselves can be used forever, it is well known that eventually the additives will falter and cause the oil to require changing. However, by "topping off", additives can be replenished. Through good filtration and periodic oil analysis, synthetic motor oils protect an engine for lengths of time far beyond the capability of non synthetics. Amsoil's unique additives packages allow for extended drain intervals.
Myth #9: Synthetics are too expensive
Untrue. Tests and experience have proven that synthetics can greatly extend drain intervals, provide better fuel economy, reduce engine wear and enable vehicles to operate with greater reliability. All these elements combine to make synthetic engine lubricants more economical than conventional non synthetics. In Europe, synthetics have enjoyed increasing acceptance as car buyers look first to performance and long term value rather than initial price. As more sophisticated technology places greater demands on today's motor oils, we will no doubt see an increasing re-evaluation of oil buying habits in this country as well.
Myth #10: Synthetic oils contain detergents that can make the oil seals leak in older cars
Untrue. Synthetic lubricants do have an inherent detergency that cleans and removes conventional motor oil deposits left over in an engine. However, motor oils are designed to help swell seals slightly to prevent leakage. The only time you would observe seal leakage is if the seals are already damaged or showing signs of leakage around them. As long as the vehicle has been well maintained, and in good mechanical condition, it can be switched to a synthetic lubricant at any mileage.
__________________________________________________
There are other MYTHS and non-truths circulating the forums, garages, and race tracks. The nine above are just a few that I wanted to address.
Conclusions
Since their inception, manufacturers of synthetic motor oils have sought to educate the public about the facts regarding synthetics, and the need for consumers to make their lubrication purchasing decisions based on quality rather than price. As was the case with microwave ovens or electric lights, a highly technological improvement must often overcome a fair amount of public skepticism and consumer inertia before it is embraced by the general population. But the word has been getting out as a growing number of motorists worldwide experience the benefits of synthetic lubrication. The wave of the future, in automobile lubrication, is here, and Amsoil has lead the march, recently celebrating their 30th year in business. For the environmental enthusiasts, the use of synthetics could reduce waste oil disposal by 80%, so if environment is your thing, then synthetic lubricants should be your choice.

Modern synthetics are compatible with petroleum oils. I've switched back and forth and never had any trouble. My only concern with the first post is that the synthetic may clean out some crud on a high mileage engine and cause a leak.
