What Synthetic oil do you use and why? and Who are the best Sintetic oil in the market?

 

Synthetic.

Mobil 1. Good reputation. Never heard anything bad about it. All I'll use now.

 

Thanks, what do you think about Eneos

 

I currently am using redline oil and I use it since it also cools my supercharger

 

Mobil 1 and Eneos if i stumble upon some extra pocket change. ive also never heard anything bad about their oil just that their filters may be a bit overpriced. eneos is a supplier in F1 so i assumed that they knew how to formulate a good synthetic. but they are quite expensive and hard to find in the regular spots (kragen, autozone etc). the closest dealer in my area is like 20 miles away..

 

Never used Eneos... so I can't say regards to that.

 

Haven't used synthetic yet, but on my next oil change I will be using Pennzoil Platinum 0w-20.

Go to bobistheoilguy.com (in the forums) & you will see it is a great oil for the price. UOA (used oil analysis) show that it is a better product than Mobil 1.

If you want the best of the best, AMSOIL is what you want to get.

 

i will start using synthetic after my 2 free oil changes
and i was thinking of Mobil 1!

 

Same here.
5w-20
Why do I use this..... easy to purchase at Walmart (open 24 hours) with a good price.

 

I use Motocraft 5-20 sythetic blend. $10.00 for a 5 quart jug at Walmart. I know it isn't the best oil out there but it is plenty good enough for a $16,000 Scion.

 

Thanks to all

 

i'm currently running mobile 1 0-30 and it's great. my engine had some noise before but once i've changed it to mobile 1 it got really quiet and i actually got better mpg, +2 - +6 depending on how i drive. highly recommended and i got it at walmart, 5qrt for $20 great deal and i went back and got more.

 

i didn't mention that this mobile 1 0-30 i'm using is formulated for increase mpg, thats why i got it in the 1st place and it really worked

 

i usually use Quaker State Horsepower with moble one filter but last oilchange i used Mobile 1 Extended Performance because i moved again and now im an hour and 60 miles each way away from work and school so i figured it would help a little more, plus im getting up there in miles and its only getting worse (i average 1000 miles a week now )

 

is it recommended to use the manufac suggested weight, or can you "stray" based on personal preference when using synth oil?

 

Im at 22k I only use Mobile 1 and there filters. Stays clean lookin for 4-5k miles.

 

How often do you guys change it? I have been going with the 5k free oil changes so far... Can you change Synthetic less?

 

IMO, no matter what oil you use, you should stick to the mileage rules.

 

In theory you can but it still gets dirty and contaminated. I have read about people that just replace the filter and top off the oil and go 25k miles or so but I would never try it. For the past twenty years I have used full synthetic and changed it every 6k or so and never had a problem. I guess I am getting cheap in my old age because I don't even use full synthetic anymore but still change it at 5-6k with a semi-synthetic. I think I will switch to full synthetic Mobil 1 0/20 or 5/20 at my next oil change to see if I can improve my gas mileage.

 

i use 5w20 royal purple love it
