#2859611 - 01/05/13 07:35 PM Shell Rotella T5 vs T6

I have a 1999 BMW M3 with a high mileage engine. It is only driven on the street but I do drive it hard some times. Right now it is using about 1 qt per 1000 miles of redline 5w30 and this is common for these engines. One of the top engine builders recommended that I switch to Rotella T5 10w40 to reduce the consumption. (I live in California where the temperature is warm) Apparently that is a synthetic blend but I would like to use full synthetic and have heard of BMW owners using Rotella T6 5w40 with good results. My oil change interval goes by the service lights which can be up to 9000 miles. Which oil would be better for me? Thanks

Andy

T5 10w-40? Not 10w-30?

Rotella is about $22/gallon at Walmart (no 5 QT jugs).

Rotella T6 would be better than T5 . Why not use a ACEA A3 spec oil or a BMW LL oil . Mobil 1 0w-40 or Castrol Syntec 5w-40 would be a good choice as well. If it is consuming alot perhaps Mobil 1 10w-40 High Mileage.

The t-5 being a semi-syn may curb consumption. I have noticed in v-twin engines that conventional oils seem to be consumed at a slower rate than synthetics.
Try it out. If the t-5 doesn't work out try the t-6

Rotella T Triple Protection is the 10w-30 flavor.

T5 is a 10w-40 semi-syn.

I own a gallon of T5 semi-syn 10w-30.

There is a rotela 10w-30, but also a T5 version...

Ive not personally seen T5 10w-40. Im not denying that it exists...

I would go T6 5W-40 with OEM oil filter and drain plugs. I stress importance of OEM filter. Check your PCV valve as well and air filter.

If that doesn't work, do same as above but instead get Maxlife blend or synthetic 10W-40.

Yeah I always use oem filter adn coolant. My pcv (oil separator) is leaking a bit so Ill replace that to help the consumption. Air filter is new. Apparently Rotella T5 and T6 works well for these engines given what they say on the BMW forums but I'd like to find out which would be optimal. I always lean toward full synth.

My Taxi has just gone past 180k miles and the OCI before this one was Maxlife Diesel10w40 synth blend.

I know this is not a similar engine but it hardly used half a litre in the OCI, which was at least 8k miles, 50/50 dual carriageway and harsh urban Taxi work.

Didn't stop me going for Mobil 1 0w40 (SN/SM) New Life this time though!

I will say I had oil consumption issues on Mobil 1 0w40 many years ago in a high mileage Omega which had the 2.5 BMW 6 cylinder Diesel engine, this was almost stopped by switching to 5w40 Comma Syner D.

I would try the fully synthetic Maxlife perhaps, but I would shy away from using Mobil 1 just in case the oil use was to increase.

The Clio (also on Maxlife Diesel 10w40) has still not needed any top ups since the episode when the oil light came on, so I suspect that was just the result of a long journey and perhaps a sensor issue, pity I wasn't there to see exactly how much oil was out in and what the dipstick level was.

Or the wife might have got the warning lights mixed up!

Tractor Supply carries T5 in 10w40, but if you're going to run a HDEO 40 weight I'd opt for the T6 between the two I believe.

So despite being 5w should the T6 be the same viscosity when hot due to being synthetic? The thicker oil should help my engine seal.
