Hi Luis, the problem is not so much the oil since you change it for POE and ready the big problem is that your engine is made to ride with R12 and its replacements such as R134 R401 R406 YH12 R409 ETC ETC but it is not made to ride with R22 and its replacements, which in this case would be R404, will consequently bring you several headaches and the breakdown of it, especially the electrical part, since by placing a gas such as R22 O R404 ((I will say again, it is a substitute for R22)) has a higher working pressure with another mass and increases its effort at startups as in its work, therefore it suffers the entire electrical system
