I was told to use synthetic oil only in my 2006 honda accord. Then read owner manual and it says 5W20. Is that the same thing? Are there different kinds of 5w20?

Any type of oil, conventional and Synthetic or a blend will come in different viscosities, like 5W-20. Conventional is what Honda recommends, but you can use Synthetic oil if you want to you in the same viscosity. Lots of debate which is better, drain frequency etc.

Now I am really confused. Dealer trying to sell me service plan. Says I have to pay more for the plan due to my 2006 honda accord using synthetic oil only. But owner manual says 5w20. Car has 160, 000 miles. I guess I'm trying to find out if he is just trying to make money on me, or is there a reason I should use synthetic.


Dealers are in the business to make money. If you have 160K and used regular oil in the past I would continue to do so. If the dealer refuses, then find another mechanic/shop to service the vehicle.

That's just it...... I have no idea what type of oil has been used thus far.......just bought the car. 4th owner. If synthetic was used in past, will it hurt anything to go back to regular 5w20?


No, it's all in the interval of changing the oil periodically more so than the type of oil.

Ignore the dealer! Just use the recommended oil, or if you have no oil leaks anywhere on the engine and want to pay the extra money for synthetic then go ahead. The dealer is just looking to rape your wallet as usual.
