It would be better. but you can get away with others

 

ill just try to find some cheaper than yamalube cause i aint payin 10$ a Q. for like 5 galons

 

Yes you should use high quality oil if you want the best lubrication/performance/longevity! The Tecate is quite high strung and a nice full synthetic race oil is beneficial. If you're talking about a weed eater, it's not such a big deal, but the Tecate is a different story. You can buy dealer brands like Honda HP2 synthetic or Yamalube at www.yamahoftroy.com for cheaper than a typical dealer would sell you in person. I use HP2 myself and couldn't be happier.
