What's your advice on motor oil?

I used a synthetic blend (Mobil 1) last oil change and I am very pleased with the product. I would like to know if a full synthetic (Valvoline SYNpower is on sale) is an even better choice or what the differences would be





Thanks in advance for your opinion! .

full synthetic is better.


How many models come from the factory with Mobil 1 full synthetic?


MANY!





Most of the cars i work on (mercedes) go 10,000 miles or more on full synthetic mobil 1. And thats what mobil 1 is designed for.


I honestly have no experience with the other full sythetic oils, just mobile 1.





It does cost more, but you get extended oil change intervals and better piece of mind. Both my cars and my bike run mobil 1 only!





but its a touchy subject for many auto hobbyists.


As everyone has there prefference.





If you change your oil and filter at 5,000 max miles, then i would think any full synthetic that meets all your specifications (basically your name brand oils) will work just fine. As a side note, make sure you let your engine idle for atleast 30 seconds or so after startup to get the oil circulated.





good luck!What's your advice on motor oil?
I am a mechanic and i have asked this same question. Today the oil is much better as i was years ago. Someone once told me oil is oil is oil. If you want to go longer on oil change intervals a sythetic is a good option. But regular oil is cheap and offers great protection also. If you have the money and want insurance for your motor then sythentic is a great option. If you can change it every 3 thousand then regular oil is fine.
Id stay with what works. Personally i would still change full synthetic at the 3000 mile interval. Oils still gets dirty if its synthetic or convetional. The only way id consider going over is if i had a top filter like a wix or a NAPA gold. Which is all i use.
when you use Mobile 1 you can never go back to any other oil because Mobile 1 makes a barrier to seal for the engine. oh and dont for get to us full synthitc form Moible 1
Full synthetic is better but also more expensive than a blend.
i use castrol synthetic
Well it works well.
