What engines fo you run??

Mobil 1 20-50
M1 filter

I have heard elsewhere that the new extended life blend (gold cap)from Mobil 1 does not have enough additive in it compared to the old Silver cap blend.

Any truth to that?

Unfortunately yes...Mobil-1 15W-50 no longer can meet all CH-4 requirements...it previously could...though they are tough diesel engine mandates they benchmarked how good the Redcap was...for gas engines//may Redcap RIP.

Mobil-1 20W-50 V-Twin is unaffected....there is no doubt that it is the best oil for your marine engines...we are hearing stories about main bearings looking too good to be true on teardown and a mechanic I spoke with in Florida said he never saw a 1050 Sterling engine look so good after 50 hours...which was a bit past normal tear-down. Know how many engines blow due to a main bearing blow out related to poor lubrication? A lot!

If you can pop near $10.00/qt it will save you a ton of money in an expensive engine. Mobil-1 20W-50 V-Twin is a totally ester derived oil. It does not have polymers to enhance viscosity. It really is a straight wt 50 that behaves like a 20W-50 when you look at the Cst's...it is the world's best "20W-50"
in my humble opinion. It won't break down ...it won't stop protecting your bearings..and it will increase oil pressure about 10 lbs and decrease engine running temps. by 10 degrees we are seeing as well.

Now in cool weather switch to 15W-50 Mobil-1....this stuff is too heavy for cool to to cold weather...it is a true hard running summer oil.

I've seen the V Twin at local Autozone's but its spendy. Anyone have a vendor that sells at a discount? Walmart, Target, etc do not stock it around here.

6 qts for $44.50

Hey it is the world's best 20W-50 ester based automotive oil that could be used in a 747....

...use Mobil-1 Goldcap 15W-50 if it's too much $$$....

...but if you are running a hopped up engine or anything over 500 HP then this is my strong recommendation.

Just bought 20 quarts M1 15/50 @ $5.36/qt (Walmart) The 5 gallon jugs were $23.82 each.

That's what I bought and put in this spring. M1 15W-50 for the price of Merc lube.

All of the Walmart Supercenters in our area (Texas) has set up little motorcycle sections in their automotive departments. They stock Bell helmets, gloves, filters and oils. They all have V-Twin for $6.88 per quart.

Saleen, that sounds like a good reason to bring your darling wife down to Texas for a visit! I'll buy you the freaking oil!!

$6.88 for V-Twin is a steal. Mobil had to drop the price to compete with Harley's brand of synthetic oil I hear.

...Mobil told me they don't have a 20W-50 labeled for auto use because it is very thick oil and as far as boating goes....they told me the anti-corrosion protection it offers is amazing as it prevents dry-starts after even a few months of storage. Mobil ran this oil in a V-Twin bike for hundreds of hours and it protected bearings and cylinders 30% better than 15W-50 redcap...and 60% better than a conventional 20W-50. I just wish they would publish this stuff...

They said the oil market is very competitive and labeling this "V-Twin" created a niche' for it to sell better.

They also said they have found that the John Deere Guys use it in heavy Farm Equiptment...word gets out fast!

I also found that 15-50 M1 1 gal was off the shelves in all 3 walmarts around here. Only quarts. How's 10-40 M1 ? They still have it in gal's
