 Subject: Sythetic oil
IP: Logged
Message:
My truck (4.7 5spd) has 74000KM on it and I am thinking of switching from 5w-30 conventional to Mobil 1 Sythetic. I has changed the oil every 6000km and all KM have been Highway driven.
Will sythetic cause my seals to leak?
Have I put to many KMs on the engine for the switch?
Has anyone noticed a performance gain in switching to Sythetic?

Switching to Synthetics in high mileage vehicles:
Q. I sometimes hear "Synthetic oils contain detergents that can make the oil seals leak in older cars." Is this really an issue? How old would a car have to be to not use synthetics?
A. 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.
*** YOU ARE SAFE SWITCHING TO MOBIL1 !!!

As to your question about improved performance ...
I suggest you do a search on this forum.

Let me explain the story behind leaking gaskets/seals. AMSOIL lubricants are all tested for seal compatibility with all the seal materials in use with industry accepted testing methods. AMSOIL Products will not damage seals or be more prone to leaking than petroleum products when used in vehicles with undamaged seals.
Unfortunately, HIGH MILEAGE vehicles and equipment that have been using petroleum lubricants for LONG periods of time face the risk that sludge and deposits have built up in the engine and created a FALSE seal, and the seal itself has dried out and cracked or shrunk. Lubricants help condition seals, keeping them supple and slightly swelled to insure a proper seal with no leaks. When covered with sludge or deposits, the seal will deteriorate.
NOW ... you start using AMSOIL motor oil with it’s high quality additive package and natural detergency, and you start to clean up the engine. The false seal is cleaned away, and if the seal itself has become cracked or damaged, a leak will develop. The same thing occurs in transmissions and differentials.
Because of this, many people think that synthetic oil is more prone to leaking, when all it really is doing is revealing the problem that petroleum oil deposits had created and kept hidden. Once the damaged seals are properly replaced, keep using the synthetic oil and they won’t leak again.

I have researched to forum
I was wondering if 74000 well maintained KMs would be considered (high)?
When My seals are cleaned by the good oil will there be crackes at 74000kms?

be considered "high mileage".
Go ahead and switch to Mobil1.
Choose your viscosity per manufacturers guidelines.

| Amsoil & Synthetic Performance
IP: Logged
Message:
VANISHING,
Let’s address performance gain using Synthetic Lubricants. Increased performance is a subjective benefit, but it can be actually measured in numerous ways:
Better cold weather starting due to lower pour points.
Cooler running at high temperatures and under severe conditions. This requires measurement of operating temperatures when using petroleum lubricants and then synthetic lubricants in the same equipment under identical conditions. A controlled test is needed to demonstrate this, and it has been proven by Amsoil and others when testing synthetics in general. Most users are able to actually see the difference in their engine and transmission operating temperatures when running under similar conditions.
Less component wear, as AMSOIL and others have demonstrated that synthetics offer as compared to petroleum. Usually this is only apparent to the end user when comparing oil analysis reports and comparing the wear metals in parts per million per mile when using synthetics vs. petroleum in the same vehicle. Certainly after many miles of use there would be a visual difference in wear in a controlled comparison of two similar engines, transmissions, or differentials.
More horsepower as demonstrated on dynameter tests comparing AMSOIL products with petroleum oils and other synthetics.
Reduced oil consumption as experienced by nearly everyone using synthetics due to lower volatility.
Reduced emissions, also due to lower volatility, but not generally noticeable by the typical consumer. And there are others. Most of these performance benefits require close scrutiny by a consumer, or a controlled test to demonstrate quantitatively.
Fuel economy can also be very difficult for the consumer to accurately gauge. Once again, it has been proven by AMSOIL and others, through use of industry accepted fuel economy tests, field demonstrations, and as witnessed by most of our customers .... that switching to synthetics DO IN FACT show a fuel economy increase = better MPG.
