octane and oil thoughts..

[Art161]

Very interesting information, metroplex. Thank you.

As for gasoline, I have spoken with auto technicians who are of the opinion that the Techron additive contained in all Chevron gasoline sold in the United States is the "real deal," and not just hype. The additive package is the same for all grades of Chevron gasoline at present, not like in the old days when the premium grade had a higher level of detergents. For those using a different brand of gasoline, you might consider adding a bottle of Techron additive at appropriate intervals.

Chevron and Techron are high quality fuel and additives (respectively) but I've never been able to find the Chevron fuel in MI or NJ. Techron gets expensive over time and I've never had the need to run any additives ever since I switched to Meijer fuel. Other gas would cause detonation very easily (Sunoco, BP, Mobil) in my area.

Nothing, other than risking damage to your engine because the oil has too much viscosity when hot.

i find it hard to believe that running 10w-30 would cause damage.... maybe if he was running 20w-50.

 

[whyask]

None the less... I found a place that sells 5w-20 mobile 1, got 6 quarts of that put some more Lucas Synthetic Oil Stabilizer and added a K&N oil filter. Now my mind is at ease ! <!-- / message --><!-- sig -->

I like the K&N filters more than anything else out there.

 

[metroplex]

Just stick with the Motorcraft FL-820-S. It's a superior filter at an affordable price. Lucas Oil Stabilizer is really snake oil. Don't use any oil additives because they're worthless. Modern oil formulations are good enough right out of the bottle.

Mobil 1 5W-20 here.

I run Mobil1 5w-20 with the ford racing filter. Royal purple for trans and diff.

IMHO the CAI and tuner is a good starting point. You will get a nice bang for your buck and you can switch octane levels. I run 87 from monday through thursday and 93 for race night. I just retune while the gas is pumping. (convinced my wife the tuner would pay for itself as I could use cheap gas )

Personally I skipped exhaust work and went for gear (4.10) with no regrets. Apparently the stock 2.5" exhaust is pretty solid.

 

[metroplex]

Save your money and use just the Motorcraft FL-820-S filter. The Ford Racing filter, Mobil 1 filter, K&N, and other "high performance" oil filters are inferior in filtration. Like the K&N air filter, you cannot have both high-flow and high-filtration at the same time. You tend to sacrifice one for the other. Unless you have a real-time oil pressure gauge that shows significant restriction from the FL-820-S, I recommend just sticking with the OEM-spec oil filter. The bypass valve and silicone anti-drain back valve on the stock FL-820-S is quite superior to most of the oil filters on the market.

For engine, transmission, gearbox, differential, and power steering fluids, any synthetic will suffice. Just try not to buy into marketing hype.

When I first got the car I had a Ford Motorsports mechanic install a FR1 performance pak. At which point Ford requires the racing filter to maintain warranty status.

That is the silliest thing I have ever heard. The only effect using slightly higher viscosity oil will have on your engine is slight reduction in fuel economy and maybe 1 hp less power output.

+1

and a bit more protection when its hot

Since you have only one post, perhaps this is the ONLY thing you have ever heard.

 

[metroplex]

IIRC the Ford GT and GT500 use 5W-50 synthetic engine oil.

I have been reading for a while without posting. I just couldn't stand the misinformation. Post count means nothing anyways.

You may have been reading for a while, but I don't know whether you understand. This is a friendly forum. We have differences of opinion about things from time to time, but coming on with your first post being somewhat rude is not going to make you many friends here.

I stand by what I stated in the post that you consider the silliest thing you ever heard.

There is no difference of opinion. There is fact vs fiction, and the statement was meant to correct what was previously stated. I was not unfriendly. It was a silly thing for someone to say. If you take offense to that, then I am not sure what to say. Most of the forums I frequent are not so sensitive. I wouldn't expect this forum to be any different.

I would be interested in having you state your "facts" as to why Ford specifies 5W-30 oil for the V6 and 5W-20 oil for the GT. So far you have said nothing other than you think my statement is the silliest thing you ever heard, but have not said anything as to why you think it is silly. Educate me.

Maybe my statement has something to do with lighter weight oil flowing through the oil galleries faster and providing improved cooling that is better for the GT engine. Maybe my statement has something to do with reduced friction that is better for the GT engine. Maybe my statement has something to do with less stress on the GT's oil pump. Or maybe Ford just wants its dealers to stock different weight oils for the Mustang V6 and GT so as to make life more difficult for the parts and service departments.

Your turn.

Slicker than 0W-20! Lots of improvement in last two games.
