Oil opinion

I'm going to switch to synthetic, I bought my truck used at 37k I is a 2010 v6. I've read somewhere that switching to synthetic causes some emu he's to develop leaks. What brand oil do you guys use other than the stealership oil? I was thinking Mobil 1

 

Mobile 1 Conventional. No need to go to synthetic, Toyota recommends conventional. If you do decide to go with synthetic there is no reason why it would cause leaks.

 

If you are going to change oil at 5000 miles then stick with conventional oil. If you are going to switch to synthetics then run the first few intervals at about 7000 miles, then every 10000 or 12 months.

 

Mobile 1 full synthetic. Runs great!...

 

Mobil 1 full synthetic. Been running it for years with no issues. I still change it every 5k miles and bought into the hype of synthetic. One thing for sure it sure won't hurt anything.

 

Mobil-1 Synthetic. Here's an oil analysis on it from my truck.

 

Quick/dumb question on the Analysis form.....

What does "Make Up Oil Added = 3 Qts" mean?

 

How much was added between changes. 3qts was incorrect though, otherwise I'd be worried.

 

Thanks....that's where I was going/what I was thinking.

 

been putting mobil 1 in my 5vzfe for 16 years, 220,000 miles...motor is 100% and still gets better mileage than the first 4 months of owning it. clean, almost zero wear. stuff works.

 

$25 at the dealership works for me

 

Pennzoil Platinum or Ultra because Mobil 1 now sucks ....

 

EEK!... What the hell is that?...

 

Click the link. Its frame rot.

 

I like Valvoline Synpower full synthetic.

Yea, I know. I had a 1st gen that got a new frame for the same thing. I was just being dramatic!...

This.
I dont do my own maintenance to save money, I do it to know what went in and quality of work. Plus when I am doing oil change I get chance to check for leaks, loose bolts, etc.

 

Exactly! I never used the free oil changes on mine, and opted to do them myself which runs me around $40 for synthetic. I started doing that on my Jeep since everytime the dealership did it, it would drip old oil for a week, when I did it never dripped anything

 

Follow manufactures recommended oil intervals...


I would never go past 6 months no matter what oil.More like 4months if you didn't make the mileage.
