Most Syntecs are not true synthetics, the only true synthetic oil from syntec is 0W-30. Every other syntec I believe is a class 3 oil. True synthetics are made from PAO/Esters. (it is an older post, so maybe things have changed)

think with your dipstick Jimmyy *smack!*

 

Thanks for the input. I have read all the threads on the site but did not find a comparison between the so called full synthetics and and 100% synthetics. "i buy ams oil for 20 bucks a liter because it gives me peace of mind" really didn't convince me Lots of people pushing 100% synthetic like ams oil, red line or German Castrol. I just cant see it being worth double the price. I'm glad to hear there are guys out there using castrol and mobil 1 full synthetics. Ill go with castrol Syntec 5w30 for now, appreciate the input.

 

thx for the site redpit10

 

Mobil 1 Full Synthetic with Mobil 1 Filter!

 

Royal Purple.

Its amazing, true 100% synthetic. Great oil. I love the stuff.

Great for high revving engines.

 

I use the same thing. Once or twice a year at Advance Auto Parts, they carry a special on Mobil 1 full synthetic. You get 5 quart and a Mobil1 extended filter for $29.99. The regular price of the filter itself is about $12 bucks.

 

If votes help you out I vote on Mobil 1. Use it on all five cars in the household.

 

I use Eneos 0-50w fully syn, expensive but well worth it, ive tried mobile,royal,even castrol and Eneos has been the best while royal sucked ***...

 

My next oil change (another 500 miles till my next change), I will use either Mobil 1 or Castrol Syntec with Purelator PureOne filter. WalMart is selling the 5 qt jug for $22. And Purelator is have a rebate on the PureOne filter right now.

I believe if you maintain your car regularly and not taking it to the track often, any recommended oil should be fine.

 

What do u guys think of Quaker state synthetic for our cars? That's what I used last time, I never hear ppl talk about it though

 

jesus, not another "what oil should i use?" thread...so painful.

 

+1 96,000 miles of hitting the redline several times daily and the engine is still in great shape with good compression.

 

Having owned several highly tuned and turbo-charged cars running huge boost with plain old Mobil 1 I think you could run a G35 on just about anything that meets the required JASO standards if you change it every 3750 miles or so. These engines are not stressed and unless you want to go for extended drain intervals you are wasting cash using pricey fully synthetic oils.

Any branded semi-synthetic (like Mobil 1) will do fine for non-race use...

 

I am switching to Mobil 1 5W-30 from oem. Keeping the 3750 intervals until I get out of warranty then Ill send it in for analysis to see if I can go for more.
