How do you think 20wt would fare under high speed conditions?

[Triple_Se7en]

I see all those folks doing 85-90 on freeways here. Then I read about them in obituaries after a deer runs-out right in front of them (or) black ice suddenly appears underneath their four tires.

85-90mph is not fast on some roads, and is blindingly scary on other roads. I might do 90 on the interstate, but I go 15-20 through residential sections ALWAYS and don't speed in school zones.

As far as the oil goes, I would run a 30wt.

If this is true then why do Ford trucks call for 5w-20? People do a lot of towing with their trucks.

As I said, it's almost impossible to safely got fast (or at any speed really) on US roads, because drivers lack discipline -- for example, they will cut in front of you if their car fits.

Maybe you should be worried about the safety of yourself and other people rather than oil consumption at 85 mph

I havn't been on a US highway yet where the left lane averages BELOW 80mph. And if your one of those doing 55mph in the left lane, you shouldn't be. It's best to go with the flow of traffic. EVERYday on my commute to work in the left lane state troopers will tailgate you doing 80mph to get past you. They don't pull people over doing this speed. Everyone does it. What causes accidents are people cutting each other off and not being in the right lane driving the right speed.

I use 5w-20 regular havoline in my 2002 mustang gt with no problems, Buster. Don't be afraid of any SM rated X-w20. It will provide more than enough protection for wide open throttle driving

Just stay safe Buster....that 295 around Philly
can be a real bear.

Having traveled a great number of US Highways for a great number of miles, I have observed that this is chiefly an urban/suburban commuter highway phenomenon. Why is that, I wonder? I sometimes see it on certain very deserted, open, flat, straight roads as well, but it's mostly urban/suburban.

I certainly agree that driving with the flow of traffic is worlds safer than 'teaching everyone a lesson' by being the only car driving 35 mph slower in the left lane.

BTW, how many miles do you drive at that speed? I'd think that the 5W20 would work fine in most cases. I'd probably run Redline, though

Mori, well said. It really IS impossible to go anywhere safely on U.S. roads. I think we make it too easy for people to get driver licences in this country. And we do not make it hard for bad drivers to keep their licences. Sad to say, it's Human Nature. People will take what they can get. If they think they can get anything they darn please, they will go ahead and take it.

"Anybody know what the total stopping distance is from 90MPH (145K/H)?

Dave"

Depends on what stops you!

 

[MolaKule]

We need need to know the mass of the car and how long it took to stop.

I gave a practical reply (estimated average figure based on average driver with average reaction time in average-mass car with average tires and brakes), axjohn gave a philosphical reply and Molakule gave a theoretical reply.

Based on this we can play "Who's your copilot?"

moribundman doesn't have a copilot, he only trust himself.
axjohn's copilot is fate.
Molakule's copilot is Newton (and probably a prayer).

 

[GoHeels1981]

Think the original question was a great one.

Here is my real life situation.

2004 Honda Accord V-6, with a Thule cargo carrier.

Just drove from Richmond, VA to Orlando, FL.

Driving in the left lane, between 80-85 most of

the trip.

Whenever I use the Thule cargo carrier I notice

that MPG drops from 30-31 on the road to 25...

suggesting wind drag makes the engine work harder.

The Honda V-6 takes 4.5 qts of oil. I use

Havoline 5w-20. I doubt I will have any problems

with max air temps for the trip being 70F.

I do wonder how the 4.5 qts of oil will hold up

with sustained 85 mph driving, increased work due

the cargo carrier, and air conditioning, if I was

making the trip in the middle of summer with the

air temp being closer to 95 F.

Any thoughts?

We run Pennzoil 5W20 in our Honda Accord V6. Do mostly (75%+) highway driving, 70-80 mph. We have had excellent UOAs, posted here (BITOG).

5w20 will work well in newer engines. My family uses 5w20 in our Crown Vics with the 4.6.Their 03 and up Vics.Its a synthic blend[Motorcraft]and sometimes Castrol.I wouldn't use 5w20 straight dino though.
