Things To Consider Before Selecting Your Oil Stop Leak
If you are new at buying Oil Stop Leak, then the number of options available at the market can confuse you. We have listed some of the important factors that you can consider before selecting the ideal Oil Stop Leak
1. Compatibility
The first thing to consider when looking for Oil Stop Leak is whether the spice is compatible with the kind of vehicle you are driving or not. For those who are unaware, all additives do not work with all vehicles. Some of the formula is not compatible with the synthetic old, while others do not go well with diesel engines. Also, there are some additives that are universal and all compatible with all kinds of motor oils and all vehicles. While choosing the additive, be sure to read all in the information section and the guide to make the correct choice for you.
2. Efficiency
The amount of the additives required for the proper functioning of the car or truck will decide whether the purchased product is efficient and effective or not. You need to check the duration for which the additive will last and also the amount of additive you need to use. The ideal additive is needed in small quantities and can vitalize the seals for ample amounts of time. So, go for that additive that will be required in limited quantities and last for a longer time.
3. Activation
All the additives require some time to activate. After you mix the additive to the engine oil, it will activate only after a few hours. The league can only be repaired after the oil stop leak is given enough time to mix with the motor oil and be activated. Sometimes, the additives do not get fully activated at a specific time. You need to run the engine for 100 miles or a little more to activate the additive and then you can stop the leaks properly.
4. Petroleum Distillates
For gasket revitalization, a very popular chemical named Petroleum Distillates is used. It is quite expensive and can even harm your engine. Before closing any oil stop leak, make sure that it does not contain Petroleum Distillates. Additionally, be sure to check that other harmful chemicals are not contained in the additives that can cause damage to the car engine. Always, choose those additives that do not harm the engine in any way and have any long-term ill effects.
5. Plasticisers
It is very important that the seal of the engine is revitalised. Generally, the leaks are a result of the gaps that occur between several seals. The plasticisers are those chemicals that repair the cracked pieces of rubber and bring them back to original sizes and forms. Make sure that your oil stop leak has this chemical in the composition.
