Synthic oil vs blend

No problem but next time use synthetic. What weight oil did they use? Your car is supposed to take 0W-20 and I do not think you can get regular or blend oil in this weight.

No, it won't hurt a thing.

Never mix oil or grease,They are become in weird consistency and do more harm than good. Before change for any other oil or grease ,make sure is nothing left from old one. Yes changing for full synthetic is the perfect idea . One of the best full synthetic oil is Mobil,the list changing consistency and chemical components with temperature change

Mixing oils is 100% OK. I have done it for well over a million miles and never have I had a "weird consistency".

Agree with F_O_R, I have mixed different grades and even brands of oil at various times and have NEVER had an issue.

I use to work as a Industrial Mechanic,with Automotive background as well ,and part of my trade was to upgrade my education so often. One of those was Lubrication . So to say nicely ,You're one of the lucky guy which NEVER seize the motor. Keep doing that GOOD LUCK ,because You need it

Mixing oils with the same API rating is okay. They are compatible. Mixing oils with different API ratings can cause some issues in some vehicles. Perhaps some more "education" would be helpful to you. Do some reading at the link...https://www.citgo.com/ConsumerProducts/Oils/EngineOilMyths.jsp

Mr Bob. Doesn't make sens to argue.Just read this below . Mixing for very knowledgeable people like chemist is o'k . But for regular "bread eaters" mixing do more harm than good. Have a good day http://www.machinerylubrication.com/Read/235/mixing-lubricating-oils

Luck is hardly needed. I have nearly 2 millions miles without a worn out engine or the slightest hint of lubrication related failure of any kind including engines . Industrial uses are a different subject all together.

Good luck again Bob. . Automotive,industrial or any mechanical or electrical/electronics applications have to stick to some principals and rules.I was in industry nearly 50 Years,and working in different country's as well . First time I heard that mixing oils or greases are O'K, If You're not qualified for. But I don't see nothing to be personal,to prove some obvious points . Good bye Mr Bob

Agree with F_O_R, industrial lubrication is an entirely different matter. Also I did not say that mixing greases was okay. Motor oils with API class SM are all compatible, but their additive packages may differ. Although I do not recommend mixing various oils, from personal experience I have had zero issues. For example I have mixed different grades of Mobil 1 with each other, I have mixed Mobil 1 with Motorcraft Synthetic blend and have mixed Castrol Synthetic with Mobil 1 and have mixed others. I have also added industrial mineral oil in small amounts to mimic the benefits of Z-Max to my engines as well as Marvel Mystery Oil. I noticed no benefit or harm with any of these. In closing I am saying, if your vehicle needs a quart of oil you can use another brand or weight in a pinch and if you get an oil change with the wrong oil type or grade I will most likely not hurt a thing.

I meant to say API class SM / SN.

I am currently using LiquiMoly 2209 anti-friction additive and while I am extremely conservative when it comes to oil additives I have been more than impressed with this product. My truck engine has 190k on it and while it ran just fine and does not use oil I researched this product and decided to try it. After several hundred miles the engine did smooth out a bit and was noticeably quieter. After a few thousand miles I noticed that the engine was really running well and had noticeably more power. I had done nothing to the engine and I could not really account for the change until I remembered the LiquiMoly.

I have personally seen benefits from using Slick 50 many years ago. Do I still use it? No, it is too expensive.
