Owner reviews for engine oil

Ravenol VMP (best oil hands down for diesel).

I red-line 1st and 2nd gear when merging onto highways from the on-ramp. But then cruise at 100 kmph on the right lane. Gotta have fun when you can! Ensure that **oil** temps are good, not just the coolant.

I have the cr150 tdi and am running liquimoly 10w60. Have not used a drop of oil running the cr190 turbo. Oil is just starting to grey ( diesel thing) after 5500 miles. 0w-40 505 mobile was burning off on me and god forbid pentosin 5w-30 507 smoked like a chimney - I got multiple engine lights having to pull over and undo the cap with the engine running, downright embarrassing. Going to attempt amsoil (not going Walmart mobile 15w-50, give me liquimoly) 5w-30 diesel and see how that works. 15w-40 works great but still barely makes it to 10k for me. I am finding it hard to run gas/diesel oils like liquimoly without a 5k interval, 7qts of liquimoly 10w-60 for $65 Amazon. Practically have to run strictly diesel specific for me, hard to find heavy duty synthetic diesel oil at common shops sometimes.

Castrol Edge 0W40 A3/B4 (European Formula), about 27$ per 5 quart jug at Walmart. Made in either Germany or Belgium. A real synthetic, Type-4 PAO based (no Type 3). Meets the strictest oil requirements from ze Germans.

Neither Castrol (OE - 5-40, or 0-40), or Liquimoly 5-40 burned a SINGLE DROP in about 5-6k miles!! Why would I buy a \"High performance\" oil, only to constantly need to top-off, like I own a crappy Harley. I never follow the crowd, Mobil included. Liquimoly and Castrol are great. Someone else made a great point. When do you ever,.....EVER see a car die or even have ANY issues caused by oil. My father had a car last 260K miles on absolute garbage oil from LubeXpress (Last meaning he donated the car with 120LBS compression, each cylinder). You will DEFINITELY see issues in your Transmission, clutch, suspension, RUST, steering, interior finishes, etc. before you will EVER see an issue related to Oil. Picture all the fox-body mustangs that are absolute TRAIN WRECKS...that still run and have power...but everything else is destroyed THAT SAID...Just make sure to use a VW spec oil in your TSI. Coking of turbo's is no joke.

Started using Liquimoly 5w-40. Wow what a difference! 3/4 qt. per change cycle. There really is a difference. Same spec as the others though.

I used to use Castrol GTX 20W50 oil with Bardahl B2 additive, but after some discussion on the Bob is the oil guy forum, I decided to try a lighter oil: Shell Rotella 15W40 without any additive. It feels a bit easier to start and runs great (but it did ran great before). However, the oil pressure is certainly lower

I had Blackstone do a Virgin Oil Analysis of Red Line 5w30 This sample of Red Line 5W/30 looks good in testing. The viscosity is just a little above our \"should-be\" range for unused 5W/30, but that's common to see with some brands, and it doesn't show any sort of problem or deficiency with this oil. The additive package is typical of Red Line. They use a lot of molybdenum anti-wear additive. There's also some silicon, which is good to know about since silicon can also show dirt in used oil samples. It's an anti-foaming additive. No moisture or solids were found. This oil is in serviceable condition.

12 Galant 2.4 always running Castrol edge 5w20 and oil filter change every 5k miles for like 60k miles now has 126k. Cars have never shut off or left me stranded or left any signs of hesitation.

I have used Mobil one for 25yrs and never had an engine problem. I have a 1978 Alfa that uses Mobil one for most of it's life when the oil was released and the engine is perfect.
