Hi, I have Tiburon 2003 V6 2.7L and I don't know what kind of Synthetic Motor Oil I must fill in my engine.Thanks

In the uk we use 10w40 semi synthetic oils( castrol magnatec)

Royal purple is the best. Ive used it in all my cars. smoother, better gas mileage, small power gain. Well maybe its not the best, but close to it if its not. its damn good oil. its Fully synthetic.

i use castrol in everything i own firm believer

03/04s they say 10w30 in the owners manual. I use 5w30 winter, 10w30 summer. The 05/06 take 5w20.

Any synthetic oil is good, just stay away from Pennzoil and Quaker State. Amsoil is the best, but its not easily found in stores. Royal Purple, Mobil 1, Syntec, SynPower are all good oils
