Oil change comin up, goin to synthetic oil. What's the best. Take your pick. Add your opinions.
Gonna use a purelator pure one filter.

 

Castrol syntech is the one oil that u would recommend to every one. I change oil every day at work an castrol is the only oil that doesn't seem to break down like others look almost like you just put in in

 

One reason I posted this. I used to use Valvoline, but switched to Castrol.

 

did you like Castrol?

 

Yes, for dino oil, but I've never used synthetic before. I used to Valvo all the time until I started noticing a drop in performance about a year or so ago. Times change and so does quality some times. Word on the street was go Castrol at the time. They were right.

 

ya i had Pensoil in my truck an when i changed it. It looked like i was about 3000 over but i was about 1000 under. That is when i changed to just regular castrol was strapped for money at the time. I checked the oil the other day an it still looked new an i have about 1000 miles on it

 

There is no BEST oil. Different oils work differently for different applications. That being said, Mobil 1 5w-30 has been proven to be an excellent performer in the Ford 4.0 SOHC engine, proven by many UOA's (used oil analysis). So has Pennzoil Platinum, and Amsoil for that matter. I use Mobil 1, based on past experience, availability, and UOA information.

You'll learn more than you ever wanted to know about motor oil! And I recommend that you use Motorcraft oil filters!

 

I voted for Castrol, but dino wasn't an option in the poll.

 

I voted mobil-1, but that's all i use. Wix filters are the only choice imo, cut open a fram or motorcraft filter then do the same to a wix filter, you'll see what i'm talking about.

 

i picked Mobil-1 cause i have used it a couple times

BUT

i now only use Quakerstate full synthetic 4x4 i love it seems to drive so much quieter and smoother.

 

as far as synthetics goes, AMSOIL is probably best hands down....

 

I voted Mobil 1. Sorry but you can't just look at oil and say it's good or bad you need a UOA to tell. This is from hot, dusty, dirty, sitting in traffic Phoenix.

i vote castrol ive been using it for the last 3 years in all my vehicle and it was used in my 300 HP 4cyl i had and never had any problems with it. and it is the only oil i use in all my vehicles. except the bike and quad have to use special oil for those.

 

I use M1.

 

YUP! That's what Scamsoil's website says!! They also lie and deceive about their API certification (only 2 are API certified, PCO, and XL)!! And on top of that, you pay a highly inflated price
for their products because of the MLM pyramid structure that puts money in so many people's pocket

 

i was using amsoil for a few years but have since switched back to mobil 1 since its easier to get for me... i dint like having to order it whenever i need some

 

Smart move! I'm sure your wallet thanks you for it too!!

 

I use royal purle and a purelator pure one.

 

I picked Mobil 1 because thats the only oil I used for 80K miles

 

I voted for mobil1 because thats what i used to use , but use royal purple now.

 

I'm at 20,000 on a single Mobil 1 5w30 Extended Performance (Guaranteed to go 15,000) and the truck is still getting the same gas mileage and running at the same temp. I'll be changing it soon to see what it looks like. I've used both Mobil 1 and Castrol and I like Mobil a lot more. I'm in the Supra community as well and Amsoil and Mobil are the two biggest used. Royal Purple is a pretty good oil as well.

 

I've used about every brand under the sun in mine and I will NEVER buy Royal Purple ($10/Qt!!!), Quaker State or plain oil ever again!

I do love my Mobil 1 10W30 and filter... about 25 bucks at most stores.

On another note has anyone used the High mileage Full synthetic Mobil 1???

 

The issue there is all you and where you choose to buy. I never paid more than $5.59 a quart for 5w30 or 10w30 Royal Purple.

 

Bob that's one thing I will agree with you on.
