Engine Oil.

Wondering what you guys think the best synthetic oil is. Right now I use a synthetic called Royal Purple in 5-30w. Whats the best for you guys?

[billytheman1188]

Ok, dont use Royal Purple, yes it is a good oil, i used it once and it was good, but save yourself some money and get the Mobil1 synthetic oil. Its about $15 cheaper and Mobil1 was rated the number one oil. I use it now and everything seems to be running fine.

i use mobil 1 EP 5w30 whats th royal purple stuff?

[Oldsnut]

Many racers use Royal Purple. Mobil spends more money on marketing.
It's all a matter of preference, they all do the job.

I use Quaker State winter synthetic (cause of weather) 5w30, summer just regular synthetic from Quaker State.

I have been religiously using Mobil 1 5W-30, but since they changed their base (and the Alero is a summer-only car now) I may switch to Redline.

i have used Valvoline SynPower since the first oil change.

i am using a cheap ass oil.. can i switch im at 48xxx does it matter if i change?

[Oldsnut]

You can switch any time, any product that helps avoid wear in the future or slows it down is agood thing.

Mobil 1 5w-30 and I started around 62K miles.

G/F's car Mobil 1 5w-30 since second oil change (Nissan requires 6000 miles before going synthic)

Delta Shell 10w-30 at 129,000 miles and a 22 year old motor (turns 22 this month :D) Syn will give the car a "heart attack" due to the gaskets and seals being so warn it
