My old 2006 987S was rock solid. Drove it for 60,000 miles and sold ($32) to my neighbor back in 2013 for 1/2 of what I paid for it. All I did to that car was wash it, put gas in it, new tires every 20K, changed the oil every 7K miles, and scheduled maintnenace. For a 987.....I'd recommend getting the S if your budget allows (more HP, bigger brakes and etc.).....skip the first year (2005).....and buy the best example you can find from 2006-2008. Good luck. Great fun Porsches.
White987S replied to hspder's topic in 95B (Macan S, Macan GTS, Macan Turbo, Macan S Diesel)My 2014 911 is accurate, within 1 mph, high. My 2016 Ford is also within 1 mph. My old 987 and993 were less accurate, within 2-3 mph. All at highway speeds.
White987S replied to immerschnell's topic in 92A (Cayenne, Cayenne Diesel, Cayenne S, Cayenne Turbo, Cayenne S Hybrid)Here's the math I promised you: Max expansion starts to happen above the 210-215 mark. I remember seeing this equation this summer: Specific volume of a unit can be expressed as The change in the units volume when temperature change can be expressed as dV = V0 β (t1 - t0) (2) v = 1 / ρ = V / m (1) where v = specific volume (m3/kg) ρ = density (kg/m3) V = volume of unit (m3) m = mass of unit (kg) The density of a fluid when the temperature is changed can be expressed as where dV = V1 - V0 = change in volume (m3) β = volumetric temperature expansion coefficient (m3/m3 oC) t1 = final temperature (oC) t0 = initial temperature (oC) ρ1 = m / V0 (1 + β (t1 - t0)) = ρ0 / (1 + β (t1 - t0)) (3) where ρ1 = final density (kg/m3) ρ0 = initial density (kg/m3) Volumetric Temperature Coefficients - β - of some common Fluids •water : 0.000214 (1/oC), •ethyl alcohol : 0.00109 (1/ oC), 0.00061 (1/oF) •oil : 0.00070 (1/oC), 0.00039 (1/oF) Hot engine ~220F and room temp ~75F and that's 145F temp difference. The oil volume expansion is then 0.00039 * 145 = 5.6% 5.6% of 9L of oil = 0.5L
White987S replied to immerschnell's topic in 92A (Cayenne, Cayenne Diesel, Cayenne S, Cayenne Turbo, Cayenne S Hybrid)You overfilled the oil back in June. Probably by about 200-400 mls. Not much, but, you're over. Some Porsches burn oil. Some don't. Normal. Yours appears to not burn oil. That's good & normal. Our oil levels CAN go UP with low usage due to combustion moisture building up from daily driving, on short trips. Oil never gets hot-hot. Can easliy be 5%. Almost a 1/2 quart. Thermal expansion is a VERY REAL issue. I'll show you the match below. That can be another 1/2 quart.
White987S replied to Beninki's topic in 991 Series (911 Carrera, 4, S, 4S, GTS, 4 GTS, Targa 4, Targa 4S, 911 50)Interesting Sportplus997. Following.
White987S replied to Cefalu's topic in 996 Series (Carrera, Carrera 4, Carrera 4S, Targa)Agree. And if you run the car in the powerband above the 4,500 rpm's during spirited driving. My cars see a lot of 4,500-6,500 rpm fun.
White987S replied to Cefalu's topic in 996 Series (Carrera, Carrera 4, Carrera 4S, Targa)Those are good numbers for shear stability. Red Line is a god product. By comparison, Mobil 0W40 would have been in the low 60's and under 12.
White987S replied to Supra-p!g's topic in 9PA, 9PA1 (Cayenne, Cayenne S, Cayenne Turbo, Cayenne Turbo S)Lots of bad advice and information in these 2 posts. First, to get the maximum benefit of the DT40 you MUST do an engine flush with Joe Gibbs BR30 for about 200-400 miles. Way too much cross pollination with other oil's additive package. Especially Mobil's. This is the exact recommendation buy the product's developers Lake Speed of Gibbs and Jake Raby's of Flat 6 Innovations. Second, DT40 does NOT have "very high ZDDP". Not much higher than Mobil 0W40. Less than 100 ppm different for zinc and phosphorus. Read the VOAs and you'll easily see. And if you don't do the BR30 flush first, your actual ZDDP will be significantly LOWER than M1 0W40. Read the UOAs to easily see this cause & effect.
White987S replied to Hayyan Al-Raisi's topic in 996 Series (Carrera, Carrera 4, Carrera 4S, Targa)Nice write-up, Hayyan, this will help future uses of this site. But your math is way off!!:) OEM 194 bulb = $4.5 Stealth bulb = $28.99 Difference = $24.49 = 544% MORE!! OEM 7507 bulb = $4.5 Stealth bulb = $29 Difference = $24.5 = 544% MORE!! OEM 7506 bulb = $9.25 Stealth bulb = $29 Difference = $19.75 = 213.5% MORE!!! I am usinf what the "cool kids" call new math.
White987S replied to sdxxx's topic in 991 Series (911 Carrera, 4, S, 4S, GTS, 4 GTS, Targa 4, Targa 4S, 911 50)The 991 is an awesome car. I hear great things about the 3.4 9A1 motor. I have 37,000 miles on my 2014 C2S with PowerKit (430 HP).
White987S replied to jroach's topic in 997-1 Series (Carrera, Carrera 4, Carrera 2S, Carrera 4S)Peppermint oil.
White987S replied to PaulH's topic in 9PA, 9PA1 (Cayenne, Cayenne S, Cayenne Turbo, Cayenne Turbo S)Use the footwell, since it's not switched.
White987S replied to racerken's topic in 997-1 Series (Carrera, Carrera 4, Carrera 2S, Carrera 4S)I'm pretty sure the Porsche spec is 1 litre per 1,000 km. That's considered normal oil consumption.
