Engine Oil......

Anyone use Red Line Synthetic oil. Just curious if you found or heard it works as well as they say. Kind of expensive at $9.49 a bottle but lasts 12,000 miles and suppose to increase HP by about 1-1 1/2 %.

Red Line, Royal Purple, and Amsoil are all quality oils. Bobistheoilguy.com is a mecca for oil and filter info. Those guys really know there stuff. Castro Syntech is also a quality synthetic oil.

Havent used red line, but have used royal purple and was very happy with it. i believe very few increased mpg claims, but on a 2005 trailblazer I realized about a 1.5 mpg increase in efficiency.

I will never use RP again in anything I drive. It seems to completely shear down to water in only a few thousand miles, making my valvetrain VERY noisy.

I just used amsoil for the first time and my car is virtually silent from under the hood. I used their "Signature Series" and will continue to use it unless something goes wrong. They have a preferred customer program for $20 a year that will save you tons of money. I got 14 botttles of SSO and it should have cost $140, but being a preferred customer I paid $100. Plus you save on everything they make.

I hear all the hype, but have stuck with Mobil 1 for the past 10 years. I can only attest to NEVER having a failure nor an issue with anything related to engine during that time. I'll stick with it ....

Howard, honestly I would stick with Mobile 1 from a priceerformance stand point.

The thing about the extended oil change intervals that are claimed... Im not buying it. If you want to take care of your vehicle, 3 months/ 3,000mi is the rule that should be followed. The way I see it, if your going to use synthetic oil, but then leave it in the engine for 10,000mi +,the oil has broken down and your losing all of the benifits of the synthetic so why bother.

The best place I have found to buy mobile 1 is at walmart, they have the cheapest prices for the gallon jug.

Just my 2 pennies.

- I agree -Royal Purple is very thin right out of the bottle(I use 10w40 not 5/30) I have used regular Valvoline for years. I am really considering trying the AMsoil. I have heard nothing but great things about it and unlike Mobile 1 its a true synthetic. Mobile 1 used to be a true synthetic but isnt anymore. If you change oil/filter every 3months/3,000 miles-conventional oil is just fine.

Thanks to all for the input especially the website.....got another 1,500 miles before I decide what to do.........thanks again.

Use Mobil 1 in the Evo, but a local shop started carrying Eneos, so im gonna be trying that (9 dollars a quart...).

AmsOil is the number 1 oil, especially for hi-po cars
Royal Purple is up there pretty close. Haven't heard too much about folks using the Red Line oil for their motors that much. but it is popular. With all the great oils out there, they still have their niche vehicle parts that they excel at.
Say, one may be better for the transmission than the other brand.
But generally, if you change oils at correct part manufacturers recommendations and stay with the type/grade intended, you'll be in great shape.
I use Mobil 1 myself for the engine, and use other brands of synthetics for every other lubricated part of the vehicle.
b-t-w where is that info on Mobil 1 gasoline engine oil not being a true synthetic anymore???
