10w30 oil, good or bad

I heard somewhere that if you went back to conventional oil from synthetic your vehicle would more than likely leak. Just what I heard from someone sometime. I have nothing to support that.

 

Alright. Just don't go and eat some Pop Rocks with Diet Coke though K.

 

I stopped using synthetic in my old GTI ('05 1.8T with VVT) it got too damned expensive to maintain that car. For a year before I traded it in I stopped using synthetic and used valvoline. It didn't leak except for when a rock put a hole in my $600 oil pan.

 

So can a 10w-30 work or not!?

 

Take it back and insist the replace it with the correct oil period.

 

Take it back after 12 years?

Giving you a hard time man. But that post was from 2009.

 

Didn't toyota make a TSB saying that any of the 1GR engines can take 5w20 or 5w30 which the what the 4.0L is?

 

There is more than 1 variant of the 1GR
I don’t participate in oil discussions, but that might give you a little bit more information that might help you.

 

Why? It calls for 5/30. My last two only had 300K miles on them though.

 

10W30 is obsolete, who the hell carries it still?

It's 5W30 but worse in cold weather. It's pointless.

I haven't seen 10W30 since 2007.

It will be fine in any 2nd gen tacoma, but I personally wouldn't run it myself because of my Canadian winters.

Edit, old thread and look at my comment haha

 

5w-25 is where it's at. best mix of fuel economy and longevity

 

I'm pleading the fifth, if that fails how about old age? Good catch, hope you all enjoyed my fau-pax thank you.

 

I’m not the guy that quoted you.
But this is the best I can come up with.
And it only applies to 2011-2015 Tacoma trucks with 2.7.
Which is not what the guy above was asking about.

I’ve done it myself. Replied to a question decades old. Don’t feel bad.

 

I only run 0w-5, until they release 0w-0 distilled from coagulated horse piss

 

NAPA for one Walmart etc.
