Oil finder / recommendation sites, based on temps?

[grndslm]

Castrol seems to have the best "Which oil should I use?" site that I've seen so far, mainly for its wide range of temperature applications...

http://www.castrol.com/castrol/sectionbodycopy.do?categoryId=9024084&contentId=7073092

But are there other sites like this?? The Castrol site lacks a number of American made vehicles and virtually all cars made in the past 10 years. I saw Mobil 1 had a recommendation feature, but it was completely void of any application of temperature.

Doesn't the owners manual list viscosity by temp. Seems to me all you need is the projected temp to base it on over the next oil change.

Most owners manuals these days just list one grade of oil to use no matter what the temperature.

Then that's the grade to use. Believe it or not, car and oil engineers are aware of the existence of this thing we call "summer."

You just use what is recommended in your owners manual. Simple and plain as that. You can use a 0w in if your vehicle recommends a 20,30 or 40grade. The link you have posted is for Castrol UK and Ireland

Valvoline's site asks for ZIP code, which I assume is to deduce climate. They also ask for mileage in order to push their HM formulations. When I put in my info for the Burb, they recommend MaxLife Syn because of my mileage and that I drive in "extreme conditions" (news to me!) due to average monthly temps above 90°F (2 months out of the year?).

They don't recommend specific viscosities though.

Mobil site in the UK usually has extra info regarding different temps.

Well in 2001 which is the newest vehicle I have it has a range based upon temp. But with 0W30 becoming more common, it can handle a wider temp range.

And when the manufacturer back specs the recommended oil, who do you believe??

The manufacturer?

Or the manufacturer?
