Synthetic vs. conventional Oil

I have a 2001 tacoma 2.7L 4 cylinder truck that's at 133,000 miles roughly. I'm thinking about changing the oil to a synthetic blend...bad idea? or should i just stay with conventional oil ? like i've been doing. Just worried that the synthetic blend may expose some leaks that weren't there when using conventional oil.

 

Just use a High Mileage Semi-Synthetic Blend.

 

Alright sounds good, thanks

 

Go full sun.
She'll t6.

 

I switched to full syn at 141,00...now @284,000 and change....no problems...just do it...

 

@bldegle2 were you using conventional oil prior to the full syn?

 

Don't understand question, I switched @141,000....reread the title of your thread starter.....
