What do you use Dino or synthetic oil???

First oil change since I got the truck. Actually this Tacoma is the opposite of my Nissan Hardbody I had.

The Tacoma is quiet when cold, and ticks when up to temp.
My Nissan would have the loudest lifter tap you ever heard when cold. I thought it was a rod knock for a long time. Best I can describe it is banging sledgehammers on thick metal. But when it warmed up, that thing was silent.


What pisses me off most is the lifter tap is most of the reason I sold the truck. It still ran fine after 35k of tapping, I just couldn't stand waking the neighborhood up every morning anymore!

 

I have been a diesel tech for over 23 years. If an engine comes with synthetic oil then use synthetic. . 1st gen Tacoma came with dino So I run dino. If you do regular oil and filter changes dino oil will be just fine. I have seen no benefit to using synthetic. I do about 30-50 oil samples on engines a month with dino and synthetic. Its all about regular oil changes......

 

Agreed. I agree that regularly changing the oil is far more important that which type of oil.

 

I had the 2nd body style frontier(98) before the tacoma. Less then 60k miles when I wrecked it . It was always silent, but same engine, 2.4l right? I knew a girl who had a hardbody that did just what your describing. Sounded like it had no oil for 3 seconds haha. An my tacoma does just what your saying. Semi quiet(lots of fan, and a flowmaster ), but ticks at temp

 

While I do agree with you about drain intervals, there are certain advantages to synthetic. Lower temps, better lube at extreme temps, extended drain periods, no oil breakdown. And most engines come from the factory on Dino to break in, because an engine will not break in correctly on synthetic

 

Plenty of High end engines come with Synthetic from the factory, no break in period needed.

 

You were doing pretty well up to this point.

The Corvette and many other performance vehicles, including BMW and Mercedes, have been coming from the factory with synthetic for over 15 years.

The 2.7 Tacoma also comes from the factory with synthetic and has since 2011.
Same goes for almost all of the rest of the Toyota line.
Only the 4.0 Tacoma, Yaris, and Avalon do not spec synthetic.

 

I stand corrected then. I was told that most engines wouldn't break it right or quick on synthetic because of how well it lubricates and to break in an engine on Dino oil

 

Well I work on lots of engines that come with synthetic from the factory. As far as benefits the truth is in the pudding. I have engines with over 15,000 hours on them we do oil samples every oil change some run dino some run synthetic. The particle counts on the dino oil is no higher than the synthetic. Like I said we do anywhere from 30-50 oil samples a month on our customers engines. So I am talking from 20+ years experience ..

 

I've been told a lot of things.
I don't believe everything I've been told.
I don't even believe everything I think...

 

There was once a time that you had to break in an engine on non-detergent oil or the rings would not seat properly.

Times have changed, and with them, engine construction materials, tolerances, and design.

Sadly, a lot of old-school shadetree "mechanics" do not keep up on progress so they continue to repeat what they have heard for 30 years, be it a truth that is no longer true, or a myth that was never true.
Every now and then I get caught on something that I was taught in the 70s and have to verify and re-think it.

 

I have learned something tonight!

 

I had the 3.0 v6.

Yep. Sounding like it had a lack of oil for a couple seconds would be the perfect description

 

She had the 2.4. And with 287k miles, she might not have had oil in the top at startup. It always made me cringe every time she started it up haha

 

This is the reason I stopped using M1 because if a tick or valve noise. I went back to Dino and no more noise.

 

Hah my buddy says the same exact thing; he was also a diesel mech for 15 years, works at irvine chevy now...my rig just hit 230k, runs great wth dino 5w30 every 3500 miles..

 

I use "High Mileage" dino oil. Seems to work well, after a few months of me changing it myself (using better oil than my mechanic) my truck has stopped leaking

 

Mine had the tick on Dino. Just seems to make it a little louder on m1. I prefer to run sythetic mostly for the extended drain intervals. I'm gonna be doing a oil analysis at 5k to see how long I can push it. There's a guy on here who was at 11k and they told him to had 2k more according to his analysis. He also has well over 300k on his truck. I think it's like 317k, and he's been doing drain intervals at about 10k regularly. That's something you can't do with Dino oil

 

Mobil 1 is notorious for ticking in the top end. I'm trying this M1 0w-40 but its still ticking some. I'm thinking about trying some German Castrol 0w-30 to see if it will stop.

 

I run Castrol 5w30 full synthetic and have no noise or leaks. But it does use about a quart every 5k miles, which is how often I change oil.
