Oil Recommendation ?

Valve train and lifter tick are are sounds that are very rare rather than a regular occurrence with 0W40. Whether this translates to reduced engine wear is another story but it sure does sound like this would be the case. If someone could direct me to the oil flow case article, it would be much appreciated.

I also track the car and only drive in summer. The thicker oil made sense to me.

I used Motul 5W-40 Xcess for 3 oil changes after the factory fill, but still had noticeable valve train noise on startup. I never used M1 0W-40 as I use that oil in the wife's MB E320 and there's always startup noise. I went with M1 5W-40 for two oil changes but had valve train noise again. I just recently went with Redline 5W-40 and the valve train noise is virtually gone. BTW, the UOAs on the Motul and M1 5W-40 oils were good, it was just the noise that bothered me.

I called Redline and they told me that their product is higher in ester than other PCMOs. Since ester is a polar molecule, it will stick to metal parts.

OK Paul I just ordered some Redline 5W-40 I will report my experience after my next oil change.

Good luck with it. I also thought about using Motul 300V, but this is essentially a racing oil and I worry about cat converter compatability. A while back I was checking RLI's oil (Renewable Lubricants) but when I called to inquire about the HTHS rating, they never really answered my question -- they gave me a long, drawn out response but since I'm not a lube engineer, I couldn't make any sense of it. They do show it as meeting ACEA A3 (1998) which has the >= 3.5cP HTHS requirement.

My engine rebuilder recommended Castrol Synted 5W40 for my Boxster. Engine was rebuilt as PO had added 4 extra liters of oil at a gas station ... she did not have a manual and read the dipstick wrong. I have used it in my 2010 F150 and it seems to run better with better gas milage. He warrants the engine and said I should not have any issues with Castrol. I am looking at upgrading to the L&N spin on oil filter kit before I put it in storage for the winter.

Back in October said I would try Red Line synthetic oil. I purchased a case from Racer Parts Wholesale (best price I could find), and with my last oil change poured 9 quarts into the Jägermobile. The first thing I noticed is on cold starts there is no more lifter/valve train noise, which is something I would hear for about 10 seconds after startup, I still have a little chain noise until the tensioners pump-up but it’s much quieter on cold start-ups. I also notice it takes more time for the engine to come-up to temperature, which was a surprise. The next thing I need to check is how much ferrous metal is sticking to the magnetic drain plug when I change the oil next time (in a couple months). I will take pictures and compare with previous pictures/amounts when using Mobil 1, I will post those results. So far I am sold.

What is the weight of the Red Line you used ?

I am currently using Red Line 5W40.

OK Danger, I just changed my Red Line motor oil and did a comparison of how much ferrous metal was on my magnetic drain plug as compared to using Mobil 1. I consistently change motor oil every 3500 to 4000 miles and ran my last oil change of Red Line 5W 40 running just over 4000 miles to make sure I had a good comparison. I can without a doubt say there is much less wear (less metal on the magnetic drain plug) using Red Line. There was approximately 50% of the ferrous metal on the magnetic drain plug as compared to the amount found using Mobil 1. I attached a couple of photos of my drain plug, one showing how much ferrous metal was on the plug while using Mobil 1 (this was a consistent amount found on multiple Mobile 1 oil changes), and the second photo shows how much ferrous metal was on the magnetic drain plug after running Red Line. Unfortunately I did not have my camera set correctly and my second photo sucks. You can still see the difference even though it’s a bad photo (I will have to make sure my camera is setup correctly next time I change my oil so I can take a better picture).

Red Line




I wish I had known about Red Line 200,000 miles ago.
Quieter startups
Motor takes longer to warm-up
Less wear on the motor

Jäger,

Glad to hear you're enjoying Redline. I have had the same experiences as you except I can't comment on the warmup time (because I never noticed it). I have a couple of thousand more miles to do before I change out the oil and get an UOA -- I'm also interested to see what the Fe levels are.
