Oil change

First oil change coming up in my newly acquired 2003 taco automatic v-6 wth 136k miles on it any suggestions on what kind of oil (obviously 5w-30) but should I go synthetic?

 

Many opinions, no real wrong answers as long as you keep up the servicing.

I would personally run a high mileage oil. But any quality 5w30 will do you good. Synthetic isn't required at all, many half million mile 3.4's out there with regular bulk oil.

 

Mobile 1 is pretty swag.

 

Thanks

 

Walmart special (usually Super Tech or Pennzoil) with a Super Tech filter has given me nearly 250,000 miles. I just buy the cheapest stuff they have. If the price is the same, I pick my favorite color bottle.

Edit: I don't use synthetic at all.

 

I just recently took a pledge to stay away from "what oil" threads, but just like the "I'll never drink again!" pledge here I go:

In San Jose, at 136k miles with a 14-year-old engine, I¹ would use 10W30 high mileage oil like SuperTech High Mileage 10W30 from Walmart (produced by Citgo).

My wife's '03 Highlander (3.0 L V6) has been running on that for 7 years and over 90k miles. Still runs like new and does not burn or leak a drop--HM blends include additive packages that can and do soften and protect hardened seals making them of significant benefit to not only high mileage, but also older engines...

------------------------------
¹- I, me, IMHO; FWIW. I do not care to argue or engage in any back-and-forth banter regarding same.

 

Take the skid plates off and give it the reach around when removing the filter.

 

I have always run 10w30 penzoil. Been using the high mileage flavor since around 100K. I'm at almost 240K now.
