My first thought when seeing this was CV system. Interested because my son purchased a 330ci ZHP car also and it just turned 100k and he also did an oil change so we'll see how it does on consumption soon. He got the prescribed full synthetic meeting the European Car BMW spec, Quaker State I think. What oil are you using?
We're getting close no oldskool happiness territory!
Now I run M1 0W40. I ran M1 5W30 for a long time, and at this point the 0W40 makes the car happier. I'll PM some other details before we turn an oil thread into an EPIC OIL THREAD!
I'm probably going to be sent to Ban IsIand for this, but I leased a Jeep for 4 years and never once opened the hood. No service whatsoever. No garage. I think it was a V-8. At least that's what they told me. Nice stereo until it just stopped working one day. -I'd lease another.
Hello I have a lovely BMW e28 5 series 1988 registered the second of March . So Beat Master Wheels birthday soon. It has done 44,668 Miles from new wife and husband owner from new with full service history. It is immaculate like it has just come out the show room completely original besides the Aplina Alloy wheels, 75 percent back three windows tinted sun strip and Scorpioin cat one impoliser. Even the cassette radio works all good . So how often do you change the oil. I have had four mk 2 Sciroccos in the past and the oil change was ever six thousand. I will be saleing this car in the summer of 2025 always wanted one. It is a blessing to drive one.
Generally 1 year or 3k miles for me.
Sometimes I stretch it out, but never more then 5k miles.
Keeps me busy keeping fresh oil in everything! Cheap insurance when you run an engine hard.
Have started to buy Rotella T5/T6 15w40 diesel oil in 5 gallon pails since I run it in two M52 powered cars.
Generally I walk through the oil isle every time I'm at Canadian Tire and pick up oil/filters if they are on sale.
All vehicles, every 5k on the 5k. Just keeps it easy, don't have to worry about what the sticker says. Did they just write the default 3k, or did they write what the manual says. etc.
Once a year for any vehicles that don't do a good number of miles. This to keep the weather-related changes in the oil system to a minimum.
With regular oil, 3000-5000 is fine. For synthetic oil, it can go significantly longer but the annual change comes into play. Blended oils, get one with proper amount of ZDDP 5000 miles is good.
Remember that part about getting an oil with proper amount ZDDP to protect the valvetrain.
I see a lot of people in this thread recommend the 20W50 VR1. Wouldn't we be better with the 5W50 version? It also has a ton of ZDDP like the 20w version (1400ppm)
Here are the differences, 20w vs 5w:
-30°C - Basically frozen - <6600
40 °C - 187 - 109
100 °C - 20 - 18.0
VI - 124 - 183
Pour point - -24°C - -39°C
I used the 5w50 in M50 racecars before with great success.
Since I posted my response above I’ve grown up a bit.
And gotten a Blackstone analysis of almost every oil change.
I changed my oil way too often before. I still think 5-7k is the limit, especially if I’m driving hard. But if I’m only doing 2-3k a year, I no longer do it annually.
