Owner reviews for engine oil

I personally have run Mobil1 0w-30 in my GSR for the past 250,000+ miles, since back in the mid-2000's.

i have a bajaj 200NS and was given same reason in 2015. i didnt pursued furthur and got Motul as it is much better engine oil than crap they use. 33k km later, no issue and i get it serviced outside.

Of course, after I bought it I dropped the oil and ran what I like to run in my cars/trucks which a Mobil Delvac product 5w-30. It’s a synthetic but it’s more used for the heavy duty market. I checked the oil some 4000 miles later and it had a reddish look to it just like yours. After the next oil change I never saw it again.

Liqui Moly 10w40 MoS2

These are old engines, they were run on garbage oil and only idiots go bragging about this, regarless the old standards included zinc and other additives no longer available today due to environmental protection regulations. Ive had 7 of those classics pre 1990s and all of them got the MoS2 treatment - the engines turn around after 2-3 oil changes. Sparkling clean. Smooth.

Yooo this happened to me, have you used a high mileage type of oil? Apparently when they start to burn up they can change to a reddish hue, I went back to normal Mobil 1 and it’s back to gold

Anyhow, BMWs are arctic tested and the mega aluminum blocks can contract to -50C and can still safely start with 0W40. So the key is 7000-10000 kms but mandatory 0w4- or a 5w30 Liqui Molly or Fuchs or motul BEFORE WINTER.

Grab a good quality 0/w20 synthetic. I'm currently using Pennzoil and a Fram filter.

I run Pennzoil ultra platinum oil and GM syncromesh trans fluid

Honestly Motorex is a good oil, but it is extremely expensive for what you get. I specialize in performing Used Oil Analysis (Worked for Reliability departments for mining outfits) and it’s just a Ho Hum oil.

I used Valvoline synthetic in my first SHO, and I am using Mobile 1 in my latest SHO. I tried Pennzoil in my 5.0 (Windsor) and all the lifters started clattering.
