Mobil 1 $10 off at Costco-New DIY to oil change

The benefit of using synthetic oil, is that it does not break down as quickly as conventional oil. (I traded my '05 diesel Mercedes for a Taco. The Mercedes had a complex oil analyzing system, using synthetic, that would indicate oil change at about 13,000 miles. It should be noted, the Mercedes uses a - fleece - filter (polyester?) which does not collapse the way most paper filters collapse.) The take away, once your Taco is out of warranty, you may elect run synthetic oil past 5,000 miles, but change the filter every 5,000 miles.

 

The ideal behind syn. oil in a diesel makes sense if you drain it too soon it does not have time to pickup the particulates that diesel engines produce. Gas engines do not produce the same type of contaminates that a diesel does. If any oil filter collapses it should have been changed 50,000 miles ago by the way the drop in filters collapse too. If you are going racing with your Tacoma you might have a use for syn. if you drive it as it was intended you don't. Engines have no "feelings" only people do. If you want the engine to last 200K+ use syn. if you only want it to last equally as long use conventional oil.

 

I know a lot of people bash on M1... including myself partially.

In my STI, you just cant use it. For some reason it burns off too quickly with the turbo and you start to hear the valves tapping at 2500 miles. Its almost scarey at 3500. And thats been tested across multiple subarus that my friends and I have all owned. We all switched to Shell T6 and it was great, and you could get 5500 out of it and the oil still indicated it had life (according to the mail in oil test.)

My wifes corolla has 135k miles. Its a 5k normal oil change - at around 55k we switched from conventional to Penzoil Platinum Synthetic. It would get tappy at around 4500 miles. And at 5k she would make sure I knew to change it. I switched her to M1 last fall, and pulled 8500 miles out of it. Corolla forums indicate you can usually get about 9-10 from it, but its been a cold winter and I didnt want to risk that high. Oil still looked good.

My Tacoma gets pretty damn tappy at around 3500-4k miles, but Im still doing the Toyota Care on it (have one more change.) Ill probably switch over to M1 at that point, Toyota's seem to do pretty well with it.

Ill probably go this weekend to get two cases just to have it on hand.
