First Oil Change

Mine is brand new as well, about a month old and I am just about at 2k miles. I am changing today or tomorrow and I am going with Mobil1 synthetic with a quart of duralube. I swear by it.

Ex: I have a car that I put duralube in it once a year. I was on a trip from Denver to Phoenix to visit a friend. Somewhere along the way there I blew a head gasket. I drove all the way there and back without knowing I had no oil. the car made it back no problems. I was going to change the oil when i got back home and noticed that it had no oil to drain. I took it to the dealership and they told me what was wrong. I put duralube in every vehicle I have owned since.

 

Good luck with that duralube, I'm not convincd it does anything positive for an engine at all. In fact, many years ago the FTC made them stop making such claims. Here are some links to that product as a subject over at bitog.

hate2work,


that may be your opinion but the fact remains I used regular oil and the only thing that would have possible enabled me to drive the 1300 miles with no oil was the duralube. People can find the negative about anything on the internet. Do a search for Jesus Christ and see what comes up. I stand on my experience and stand by using it. So if you think it is a hoax that is your opinion.

 

Then why even bother putting oil in your rig? Now that you've got duralube in there, who needs oil? LOL Man, that stuff is gonna save you tons of money!!

The best part is that you drove 1300 miles without ever checking your oil

 

do you really believe this?

 

that's what's funny! just ensure there's oil in your engine and you don't need duralube...

 

Does anyone think that eventually dino/petroleum-based motor oils will become extinct? And synth oils will become the standard, the only type available? I plan to continue using only high-quality dino oil as long as it's still available.

 

You can switch back and forth all day long. How do you think they make blends ? If you don't believe me ask Chris and if you don't believe him - well I'll be polite and leave it at that.

 

exactly if u read the bottle it even sais synthetic may be mixed with any other synthetic or conventional oil.

 

OK you can mix synth with dino or blend. Would there be any problems mixing different grades of the same brand? For example, mixing 4qt Chevron Supreme 5w30 with 1 qt Chevron Supreme 10w30? I ask because I have some 10w30 to use up but Toyota recommends 5w30.

 

I've heard it's bad to mix weights, but I honestly don't know why. 5w30 and 10w30 are basically the same at operating temperature, but when cold, the 5w30 does not thicken as much, so maybe they don't mix well. One quart probably wouldn't hurt anything, but I wouldn't take the risk with my truck. JMO.

 

u can if its warm outside. if u look in your manual there is a chart. 10 30 is fine as long as temps are above freezing. so unless your in north pole in april you'll be fine.

 

It is true that switching between synth and dino will not cause dammage. Synth has it's benifits especially in cold climates. Starting an engine at -30 or colder is the hardest thing that you can do an engine. Synth stays a liquid at the coldest of temperatures. Dyno oil becomes glue at -40.

One thing to mention. My father who rebuilt engines for 35 years swears not to change the type or brand of your oil for the life of the engine. Pick one and never change. It isn't the oil, it is the additives, and mostly the detergents in the oil that differ from one brand to another. Crap builds up in engines over time, changing oil brand can cause the "new" detergent to free up that crap and that can do dammage.

For me dyno oil all the way until the engine is thoughly broken in. 10,000 miles. Then Synth of the same brand. I have asked the dealership what brand of oil they use so I can stick with it. Interesting they told me it was Toyota oil. My response: Toyota is not a petrolium company, what do they buy. "Gulf / Petro Canada" is what the dealerships use in Canada. They have country wide contract. I am not impressed by that!

Best Practice: stick to one brand

 

Someone on this forum once said that Toyota oil is made by Mobil. I know GM and Honda oil is Mobil, but I haven't confirmed that Toyota is.

 

I changed mine at 600 miles with Mobil 1 0-20w and can only find it in the 1qt bottles.

 

If this was the case, wouldn't it be better to switch brands every oil change? That way there aren't any major deposits because all the different detergents took care of them.

I'm not saying that's correct, but saying that you shouldn't change oil brands because the oil you've left in there has its own individualized deposits seems kinda backwards to me. One of the main reasons to do frequent oil changes is to minimize deposits, right?

 

I'm changing mine at 1500. I love my new taco!!

 

It's OK to mix but you should treat it as mineral oil and not run an extended OCI if that's what you're aiming for.

What is something to look for is how long your oil has been sitting around, especially if it's been through several cold cycles in an unheated garage or shed. I was reading about this just recently: going cold forces formation of waxes in the oil that degrades it's lubrication properties...this happens even to synthetic oils. And just sitting on the shelf at room temperature it can happen too. Apparently, oil should have a shelf life.

 

There is a break-in section in the owner's manual. The highest-milage item in the list, if I remember correctly, is a no-towing recommendation for the first 1000 miles. Looks like a good time to do the first oil change.

 

You guys need to stop wasting oil by changing it out early. The manual says change it every 5K miles. If there are any metal shavings, the oil filter will catch it.
